When I change the time of the Auto Lock to any time, for example, 30 sec, the Lock always auto-lock at the 3-minute mark.
No matter what auto lock I select, it always locks at 3 minutes.
You may have already tried this…
Toggle OFF the Auto Lock. Back out of the App then go back in the App and turn ON Auto Lock.
This make it work, but after some time goes back the the 3 minutes default time
