Game Center not working since upgrading iPad 2 to iOS 9
Since updating to iOS 9 have been unable to load Game Center. The application starting in its own just leaves a white screen.
if you select Game Center from the settings menu, just get a spinner.
this prevents a number of games loading.

the iPad has created its backup since the installation, so do not feel like doing a factory reset yet.
