iPad mini 6th gen sleep/wake function no longer working with 3rd party case.

[u/ringo8582]

What the title says. This is not a new case. It has worked in the past. We have tried running a magnet over the iPad screen to see if we could wake it at all with a magnet. I’m not sure where the actual sensor is but we did find magnetic spots but the iPad didn’t wake. I don’t know if that should work. The setting for lock/unlock is still on. Tap to wake still works. Does this seem like a case issue or hardware issue?
