Hello, did you end up fixing your Face ID? My phone is displaying the same msg

Hello Support, you are not answering the question here. What does it mean when we follow your instructions but it says "Face ID is Not Available. Try setting up Face ID later."?

If you still need help, reset Face ID, then set it up again. Go to Settings > Face ID &Passcode and tap Reset Face ID. Then tap Set up Face ID to set it up again.

If Face ID isn't working on your iPhone or iPad Pro - Apple ...

Do you have a disabled Face ID alert on your device?

Please read the "What to do Next" section in this link, if nothing works as per the instruction given in this link --> If an alert says Face ID has been disabled on your iPhone or iPad Pro
