Signing in with LINE no longer leaves customers stuck when their saved sign-in has expired or is no longer accepted.
- The app now clears the rejected sign-in and starts a fresh LINE sign-in automatically, instead of showing an error every time the customer tries.
- The retry happens once, so a customer never gets caught in a repeating sign-in loop.
- For customers who open your studio inside the LINE app, their LINE session is kept rather than signed out, so they can carry on booking straight away.
