What to try when Apple/Google sign-in loops.
Open the App Store and check for an update.
Double-tap home / swipe up and flick Quieta away, then reopen. A fixed build (145+) should handle this without the force-close.
If Apple stalls, try Google. If both stall, use Trouble signing in? on the welcome screen for a magic-link email.
Email support@quieta.co with the device you're on and the provider you tried.
