I thought I had issues, but I did not. I use the phone every day, no problems. HOWEVER, I have both "Require Attention for Face ID" and "Attention Aware Features" turned off. The first, because I use the phone a lot in the car where I frequently wear sunglasses, and somehow the unlock works much better with this unchecked, and the second, because I have my phone at my desk, and if I have the first option unchecked, and the second checked, my phone never goes to sleep anymore, which I don't want if I don't use it. In any case, that's how I am using it right now, and I have no issues.
