Face ID not available
When I bought my iPhone 12 Pro Max last mont, I set up my face ID and it worked perfectly for a month and a few days and then all of a sudden it’s not working and asking just for my passcode to login.. I went to reset it and I phone asked me to put my face in the frame. I did that and press continue but nothing is happening. can anybody please help? The phone is updated all the way.
Thank you.
iPhone 12 Pro Max, iOS 14
