Common Mobile Banking App Complaints & How You Can Fix Them

Written by Preston Packer | Apr 10, 2025

Mobile banking apps are no longer a perk—they’re the primary way many members interact with their credit union. But even with widespread adoption, they’re far from perfect. From glitchy interfaces to missing tools, members frequently share frustrations that, if left unaddressed, can erode trust.

The good news? These complaints offer valuable insight into what your members actually want. Let’s explore some of the most common pain points—and how your credit union can proactively address them.

Top Mobile Banking App Complaints

When Technical Issues Break Trust

One of the most frustrating things a member can encounter is an app that simply doesn’t work. Whether the app freezes during a mobile deposit or crashes during login, technical issues create a sense of instability that’s hard to shake.

And worse? Members rarely report these problems directly—they just stop using the app.

What helps

Regular performance testing across devices and operating systems is a must. But going beyond that—by integrating predictive analytics—can help catch bugs before they disrupt the member experience. Your mobile app should run as smoothly on an iPhone 8 as it does on the latest Android.

 

Poor Design = Poor Experience

Members shouldn’t have to “figure out” how to use your app. Yet many interfaces are packed with outdated menus, inconsistent navigation, and buttons so small they feel like a dexterity test.

Here’s a quick test: If your app requires a how-to guide to complete basic tasks like checking a balance or transferring funds, it’s time for a redesign.

Better UX starts with:

  • Regular usability testing with real members
  • Streamlined menus with plain language
  • Accessibility features like larger tap zones and scalable text

Even simple improvements—like reordering menu items or adding a persistent navigation bar—can dramatically improve usability.

 

Security That Doesn’t Get in the Way

Members care about security—until it starts to feel like a barrier.

Biometric login that doesn’t work, overzealous fraud protection that locks accounts, and confusing two-factor prompts all turn peace of mind into pure frustration.

Striking a balance means:

  • Offering alternative logins (PINs, passwords, biometrics)
  • Using transparent fraud monitoring with real-time alerts
  • Making account recovery quick and straightforward

Security should feel like a guardrail, not a roadblock.

 

Mobile Deposits That Actually Work

Mobile deposit should feel magical—snap a pic, and the money’s in your account. But when it fails? It’s one of the fastest ways to irritate a member.

Members often face unclear instructions, confusing error messages, or long wait times for their funds. A small mistake in the endorsement can derail the entire process.

A few improvements go a long way:

  • Use AI to improve image recognition
  • Offer real-time feedback on check quality
  • Provide clear, concise instructions in the app
  • Automate the review process to speed up availability

A smooth mobile deposit experience builds trust with every check.

 

Support That Solves Problems

The irony of a mobile-first experience? When things go wrong, members often feel like they have nowhere to turn. Unhelpful chatbots, endless phone trees, and support reps who default to “user error” don’t solve problems—they multiply them.

What members need is fast, humanized help.

Strong digital support blends:

  • Smart AI that can escalate complex issues
  • Easy access to live chat or phone support
  • Staff trained to troubleshoot app-specific questions

Sometimes a real person with the right tools is the best technology you can offer.

 

Transaction Errors That Create Panic

No one likes to see duplicate charges or missing funds. But these issues can be even more alarming when they happen in a digital space where members can’t walk into a branch for help.

International transactions, too, are a recurring pain point—many members don’t realize they need to enable those features ahead of time, or they’re caught off guard by foreign transaction fees.

How to reduce the panic:

  • Strengthen monitoring to detect and reverse errors quickly
  • Send real-time transaction updates and alerts
  • Provide step-by-step guidance for international usage

Transparency and communication are key here—don’t leave members in the dark.

 

Missing Features That Matter

Some members log in only to find the tools they need... aren't there. Maybe they could apply for a loan on your website—but not in the app. Or perhaps the budgeting feature they relied on quietly disappeared after the last update.

When a mobile app feels stripped down or inconsistent with its desktop counterpart, members start to wonder what else is missing.

Credit unions can avoid this by maintaining a transparent feature roadmap and communicating updates clearly with members. Proactively gathering feedback helps ensure you're building what your members actually want. And making sure your mobile platform keeps pace with desktop functionality sends a strong message: we’re here for you, wherever you are.

 

Poor Communication Leaves Members Guessing

“Why didn’t I get an alert?” “When did that policy change?” These are common questions that stem from a lack of real-time, proactive communication.

Whether it’s a fraud alert, a declined payment, or a policy update, the when and how of your messaging matters.

Smarter communication includes:

  • Timely push notifications for key account activity
  • Clear in-app banners for urgent updates
  • Email follow-ups for major changes or alerts

In a digital world, silence feels like neglect.

 

One Size Doesn’t Fit All

Your members have different preferences—why force them all into the same experience?

Some want to customize their dashboards so the features they use most are front and center. Others prefer to fine-tune their notification settings to avoid alert overload. And then there are members who’d rather hide certain tools they never use, keeping their interface clean and simple.

When your app doesn’t offer flexibility, it can start to feel outdated or even irrelevant. But with options like drag-and-drop dashboard layouts, adjustable spending alerts, and personalized display themes, you give members the freedom to shape the app around their habits and goals.

Members feel more connected to digital tools they can make their own—and that sense of ownership translates into long-term engagement.

 

Weak Integrations = Missed Opportunities

Today’s members don’t just use one app—they use several. Budgeting tools, payment apps, investment platforms… the list goes on. But if your mobile app can’t connect with them? That’s a problem.

Members expect their credit union to play nicely with others.

To create a connected experience:

  • Strengthen APIs for smoother third-party integration
  • Offer guidance on connecting external apps
  • Monitor integrations for bugs and broken links

Your app doesn’t have to do everything—just work well with everything.
