PowerApps suddenly began failing on my Samsung Android phone. The app works correctly on Windows 10 (Browser) and on IOS. It suddenly stopped working on Android. I have a home screen icon that is used to launch Power apps; on launch, the Power Apps splash screen and logo appears for a few seconds, and then the app just silently closes. If I clear the data and cache on Android for the app in the system settings, I have to re-supply my credentials, but then it works. However, after I close and re-open the app the next time, it silently fails again until/unless I once again delete the data and cache.
Removing and reinstalling PowerApps from the Google Play store does not cure the problem.
