Hey @AlyRowe, are you still experiencing this issue? If so, please allow your tablet to run out of battery until it turns off completely. Then charge it for 30 minutes with the original charger and turn it on again.

No problem. If that doesn't work either, I recommend having the tablet inspected by an engineer for repair. You can book this here or by contacting Technical Support.
