Here my problem, I beg one of you to help me, I'm at the end of my tether. I have a iPhone 6 Plus 64GB. I updated to 9.1 and since then I can't download or update apps, use apple music or backup to iCloud. It's a total nightmare. Things I have tried to fix it so far Wipe and restore via iCloud Wipe and restore via iTunes Log out of App store and back in (logging back in did not work until I restarted the phone via hard two button reset and the prompt came up, logging in via the App Store in general settings never seemed to work) Log out of iCloud and back in I have no idea why this is happening, any help will be appreciated no end!
