Verification Failed: There was an error connecting to the Apple ID Server
I have an iPad that all of a sudden has not let me used any apps and always asks for my Apple ID to make them work. When I plug in the correct Apple ID, the screen pops up saying: “Verification Failed: There was an error connecting to the Apple ID Server”. This happens many times in apps like Netflix, YouTube and Messages. I cannot use my iPad at all. Please help. Thank you!
iPad Pro, iOS 12
