ibooks is frozen on a document
I’ve downloaded a document to iBooks on my iPad Air2. Now it’s frozen on the document. I can’t close the doc or move to either my library or another document. Other apps work fine but even shutting down and rebooting has not solved the issue And I can’t delete the document either. All I can do is read it. This occurred after I upgraded to ios12.0.1 not sure if that’s the issue. Does anyone have any suggestions?
iPad Air Wi-Fi, iOS 12.0.1
