'Unable to activate Face ID on this iPhone' after 14.7 upgrade on iPhone X
Once my iPhone X restarted after the iOS 14.7 update, I was prompted with the message 'Unable to activate Face ID on this iPhone'.
Following https://support.apple.com/en-us/HT208114, I've restarted, hard-restarted, reset Face ID. When trying to 'Set Up Face ID' in settings on the iPhone, it says 'Face ID Is Not Available - Try setting up Face ID later'
Before the 14.7 update Face ID was working perfectly.
Next troubleshooting steps?
