Fixed! 
Android App (20.0.12) Crashing
This is a beta only issue.
We have located the crash and have a fix but it’s waiting on approval from Google. Please note that this is only happening right now on the beta version (20.0.12) of the app. If you’d like to leave the beta you can do so via the Google Play Store. Ensure that you have truly been removed, as Google has to do this. (It can take a few minutes.) Then reinstalling the production version (20.0.11) of the app will eliminate the crash.
