The add user and add guest buttons on the lock screen of my lenovo tab p11 are disabled after leaving my tablet for a week.
I have turned on the ability to add a guest and new user from the lock screen in the settings. This lets me add a guest or a user by clicking the button on the lock screen as you would expect. However, after leaving the tablet for a week the add user and add guest buttons are now greyed out and disabled.
The number of users has not been maxed out as no users have been created.
If I log in as the main user and then restart, the buttons are enabled again. but this is not an ideal solution for me.
