Sent an email to them this morning regarding this very issue.
Ring app ver 3.22.1
Android 10 with security patch level Jan 1, 2020
Google Pixel 2 XL phone
Full network signal on phone
App has been working fine until this morning when I tried to enable the motion settings on my indoor camera. App froze, so I cleared cache, cleared storage, reset the app, uninstalled/rebooted/reinstalled the app from GPS, and it just freezes on the user login screen. No response from app and never logs in. Web interface is working just fine and I can play previously recorded video. Just seems to be the Android app that’s having issues.
