Instead of uninstalling, what I did was to clear application data.
On my device (Samsung):
- Press and hold app icon
- Tap on 'i' icon to go to app info
- Storage
- Wipe/clear cache and data.
Done. You have now a brand new installed app.
At the time of writing, I could not find a loggout method within the app.
Thanks for step by step on how to recover. UI was not that great.
