Hi there! I understand your AlayaCare app is frozen on your iPhone, and the Face ID isn't working to get you off that page. Let's try to get this sorted out together.

First, can you confirm if you’re stuck on the login screen or somewhere else in the app when this freezing happens? Also, have you tried force closing the app already?

Meanwhile, here are some initial steps we can try to resolve the issue:

1. Force Close the AlayaCare App:
- On your iPhone running iOS 18.5, swipe up from the bottom of the screen and pause in the middle to open the app switcher.
- Swipe the AlayaCare app preview off the screen to close it.
- Then open the app again and see if Face ID works normally.

2. Restart Your iPhone:
- Hold down the side (power) button and either volume button until the "slide to power off" appears.
- Slide to turn it off, wait for about 30 seconds, then press the side button to turn it back on.
- Try launching the app and using Face ID again.

3. Check Face ID Settings for AlayaCare:
- Go to Settings > Face ID & Passcode.
- Make sure Face ID is set up and enabled for the AlayaCare app.
- Also, open AlayaCare app > Settings > Login Preferences and ensure biometric login is enabled.

4. Update or Reinstall the App:
- Go to the App Store, check if there is an update available for AlayaCare.
- If the app is updated but still frozen, you can try deleting it and reinstalling from the App Store.
- To delete: press and hold the AlayaCare app icon, then tap Remove App > Delete App.
- Reinstall and try logging in again.

These steps often clear up temporary freezing and Face ID recognition issues on iOS devices with the AlayaCare app.

If you have tried any of these steps already, let me know which ones so I can suggest next advanced options like clearing cache, checking server status, or account-related concerns.

Are you able to try these? Let me know how it goes!
