Screen cover lock/unlock not working
I have a 2018 iPad 6th generation. I have tried 4 different cases that are known to work with the lock/unlock feature (one of them I the Logitech with keyboard Apple sells) and none have worked. I have gone into settings > display and brightness and ensured it was toggled on. I have turned the feature off, restarted, turned it back on, restarted to see if it just needed a slight kick but nothing. I have ensured that the iPad is running on the latest updates and I have reset it TWICE but still nothing. It seems the only thing that switch does now is disable the lock from power button if it’s toggled on. It used to work but now I don’t know what happened. Someone please help I would greatly appreciate it.
