Hi there! I see you're having trouble logging into the Westerra Credit Union app on your Android device because it says the app is under maintenance. Let's work through this together.

First, could you please confirm if this message started appearing recently and if you’ve been unable to log in since then? Also, have you tried restarting your device or checking for updates to the app on the Google Play Store?

Meanwhile, here’s a step-by-step approach you can try:

1. Check for App Updates: Open the Google Play Store, search for the Westerra CU app, and see if there’s an available update. If yes, update the app to the latest version.

2. Restart Your Device: A simple restart can resolve temporary glitches that sometimes occur after updates or during maintenance periods.

3. Wait a Little: If the app is under scheduled maintenance on Westerra's side, logging in won’t be possible until the maintenance completes. These updates usually are brief and necessary for security and performance improvements.

4. Clear App Cache (for Android 10):
- Go to Settings on your device.
- Tap Apps & notifications.
- Find and tap Westerra CU.
- Tap Storage & cache.
- Tap Clear cache.

This will not delete your login info but can resolve cached data issues.

5. Check Internet Connection: Ensure you have a stable internet connection (Wi-Fi or mobile data).

If you've gone through these steps already and still can’t log in, it might be because maintenance is ongoing or there’s a server side issue. You can check Westerra's Member Assistance Resource Center for any updates or notices about app maintenance here: Westerra Member Assistance Resource Center.

If the problem persists beyond normal maintenance windows or updates, it would be a good idea to contact Westerra Credit Union support directly at 303-321-4209 or 1-800-858-7212 for more detailed assistance.

Would you like me to guide you through clearing the cache or checking for updates on your device? Also, let me know if you see any specific error messages besides the maintenance notice.
