Arguably the biggest feature omission holding back use-cases at this point. The current web based apps are better than nothing but just the simple fact I constantly get signed out on them some reason is enough to deter me from even opening them.
Sorry to hear that.
I assume you re-installed the app and restarted your mobile device.
I am on Android 10 with the version of the 3rd of August 2020 and works fine.
You might share the details of your OS, version and app version with the Codans at firstname.lastname@example.org
Of course it will be appreciated if you share details on what caused your crashes when your case is debugged
