Hi, I have a M1 iPad Pro 12.9" on my desk. Under the same condition, most of the time (let's say 75% of the time) it failed to identify me and asked me to enter the password. For example, it fails now and I enter the password to login. Then, I put it back on my desk and pick it up again. It recognizes me and logins automatically. Then, I put it back on my desk and pick it up. It fails to recognize me again. How come? Is there a way to improve its ability to ID me?
