Hi, i had Ipad OS 15 beta 2 installed on my 2nd generation Ipad pro 11", i was switching from app to another till the screen got darker and stuck with no action can be taken however, i tried to force shutdown and then the loop remained stuck. Immediately, i connected with my itune but didn't succeed as it is asking me to authorize the device while i am not able to do anything since the Ipad was stuck! 1 hour later (the screen still stuck), it came to my mind to erase the Ipad when i discovered that the Ipad is still sending the location. I made such action from my Iphone and thanks God the Ipad restarted again as it is new (currently i am restoring the latest backup).
