Just updated to iOS 10.1.1. It was actually by accident - after many many dismiss update windows I hit yes instead of no and the update proceeded overnight. It hadn't installed but at that point CL already would not open so I went ahead and completed the installation. Everything works but CL. I get an oversized view of the load screen, then a normal view. The Game Center welcome comes up, the bar loads all the way t the right, then I'm bs k on the home screen.
I'll open a ticket too, but advice would be welcome. I have an iPhone that does not have the game now and I wonder if I should try to recover the game there.
Wish me luck!
