Bug report - Deleting doorbell from Ring app makes the app unhappy

Ring app (iOS 15.1, iPhone 11) got unhappy after deleting a doorbell and trying to add a new one. Steps: Moved out of house, disconnected Wifi, can no longer access old doorbell. Opened app, went into settings to delete the old doorbell (Wow, I had to go awfully deep into settings to find the Delete button) Screen now lists no devices, and has an "Add a Device" button . Clicked it. Screen went fully white, nothing on it. App is locked. Force quit app and launched again, same thing. Had to Delete app from phone and delete all data, and reinstall app. Then when I launched the app it had a prettier screen than before with lots of icons and option to Set Up a Device (not Add a Device)
