I have an iPhone 5s and an Ipad pro, today I made my own apple ID rather than using the family ID, when I tried to change my game centre it let me log in but it won't let me make a nickname, every time I try it reverts back as if I haven't signed in. I have. Tried reseting network settings, reseting all settings, turning it on and off, pressing the home and lock button together to reset, and the problem hasn't changed. I turned off wifi and tried it on my 3G still no luck... Any ideas?
