At first, when the screen showed "not charging" and there was no mirroring, we thought it was the connector being faulty. Swapped it out at the Apple Store and still, no mirroring on the TV and "not charging" occurs. Realized this happened after I updated it to the latest OS 8.x; could be coincidence; but anyone else have this issue/fix? Rebooting has no effect. Any way to "undo" the update so I can get the functionality back before The Tour is over?
