Internet works but cannot download or open apps
I replaced the digitizer of an iPad Mini 3 and afterwards the customer came back and his apps cannot be opened. It closes right away. I restored the ipad to the newest iOS 12.4.9 and I can sign into iCloud but not into appstore. It looks like it is signing in but then nothing happens. Same with downloading apps. It asks for my password and then nothing happens.
Ist dies eine gute Frage?
