Help, my iPad flashes a purple screen, restart, and then the battery won't charge
Hello, I'm new with iPad.. Just bought an iPad Pro 2021 11" like in January 2022
The Chronology:
Two days ago, i was using Goodnotes on my iPad and then the iPad flashes a purple screen and restarted. When it was on again the battery was suddenly displayed at 0% and wont charge. I put it in my bag and then went doing some works. When i got back to my iPad it magically showed 71% (i didn't charge it). And it worked normal..
well.. until like half an hour ago when the same thing happened
it flashes a purple screen, restarted itself, and now it still in 0% battery and wont charge..
Can anyone help? Thank you
iPad Pro, iPadOS 15
