I have an iPhone 7 running iOS 12.4.1. Updated Ring app to 5.18.3. When I opened it, it was acting like a new install—asking me to log in and scan QR code. WORKAROUND: I stopped, closed app, and tapped one of the on screen notification for activity pre-update. App opened and everything was normal.
That is interesting, thank you for sharing your experience with us @ThatGuy97 . We will share this with the team right away! Are there any screen shots you can provide or has this occurred since the one instance?
Only occured one time, just after I updated the app
