Hi there! It sounds like you're experiencing an issue where the app shuts down when you try to enter your banking information. Let's work through this together.

1. Check for Updates: First, make sure that both your Credit Convey app and your Android OS are updated to the latest versions. Sometimes, outdated versions can lead to crashes. Go to the Google Play Store, search for Credit Convey, and check for any available updates.

2. Clear Cache: Sometimes, clearing the cache of the app can solve crashing issues. You can do this by going to:
- Settings > Apps > Credit Convey > Storage > Clear Cache

3. Reinstall the App: If clearing the cache doesn't help, you might want to try uninstalling the app and then reinstalling it. This can refresh the app's files and resolve any corruptions.

4. Check Internet Connection: Ensure that your internet connection is stable. Try switching between Wi-Fi and mobile data to see if the problem persists.

5. Verify Banking Credentials: Make sure your banking credentials are correct and that there are no issues accessing your bank’s site outside of the app. It can help to log into your bank's website to confirm everything is working on their end.

6. External Sources: If these steps do not resolve the issue, I found some discussions online where other users encountered similar problems. You might find additional insights there, for example, on this Reddit thread discussing issues with Credit Convey: Something wrong with Credit Convey?
