Same
Hey nostr:nprofile1qqsfy229w70e8lgtxavlz9t78k06yrel6fxyhreteafqet8kfxhhwmg2c6av2, Iโm not sure if Iโm the first to report this, but after auto-updating the iOS app, FaceID no longer works and it wonโt let me turn it back on. Fortunately I remembered my PIN code.
Do I need to completely wipe and reinstall the app to get this working again?

Well, I figured out a workaround. It just requires deleting the wallet and restoring it from the seed phrase or QR code backup.
