9.1 Problems? Can't use music? Can't download/update apps? GameCenter broken? Look here

Partially it works, because it corrects the error but must not make the solution.

You have found what we have all come to know. There is a problem with OUR PARTICULAR Apple IDs and iOS 9.1 and the app/iTunes Store. This was never a problem with iOS 9.02. This only affects a very tiny percentage of users. This is why Apple support and store support personnel don't know anything about this and don't know how to approach it. There is no hardware problem. It doesn't matter if you reset your phone as new or get a new phone. As long as you use iOS 9.1 and have one of the problematic Apple IDs there is nothing, repeat NOTHING you can do about it. It will have to be fixed by Apple and they are, at this point, clueless as to how to fix it or, don't really care because it affects so few people. If you can get a new phone with an earlier iOS, do it and DON'T UPGRADE TO 9.1. You can't downgrade to 9.02 because Apple has stopped signing it.

I can temporarily fix the issue of all my iTunes-related services breaking by signing out of iTunes in Settings, rebooting, and singing back in. It usually breaks again within a day, though. I imagine you can fix it more permanently by singing in with a different Apple ID, but I am not willing to do this.

I've got THE fix for this bug. Follow these instructions TO THE LETTER:

1. Sign out of App Store account in Settings.

2. Stand on your left foot with your right eye closed while restarting your iPhone.

3. While saying "Abracadabra" three times go to settings and reset network settings.

4. Sign into App Store account while saying five Hail Mary's.

5. Check to see if you're phone is working normally.

6. Reset your phone five more times.

7. Check your phone again.

8. Pray to the Apple ID gods.

This method is GUARANTEED to work just as well as every other "fix" on here.

One of my associates asks how much free storage you have. From what you said I think the phone is mostly empty, but it's worth asking, as you said that Music works, and it can take a lot of space. Go to Settings/General/About to check.

Zubcut your thing really did the trick, no idea how you came up with this. I may have been standing on my left foot with my right eye closed, though, hope that doesn't cause any issues with the cache down the line.

in all seriousness though, wdmc you've got way too many steps in your workaround there, just logging out of Apple ID in iTunes and the App Store should do the trick. You may have to reboot, but I didn't have to. I've been BEGGING people on these forums to stop advising people to do wipe-restores - it doesn't fix anything and in my case I lost a boatload of third party app data because my phone was unable to back up/reload the apps properly, the link to the App Store being broken and all. Wiping and restoring is a 100% waste of time.

Oh I see, that makes sense. Surprised just logging out doesn't work for you, just tested it and a simple log out made all the issues evaporate after a reboot (not restore)

Same problem... was writing on another thread.

Apple Music not working on iPhone 6 after iOS 9.1

(Some 24 pages there!)

Done a lot of things, none worked.

Been calling Apple Support in US (I am in India) - they seem to have heard it 'first time' - strange!

They do make you go all the steps of restore, blah blah...else they 'will not work with me' on this... so one is forced to do that (and I nearly lost all my data doing that, coz there was some issue in the backup/PC /itunes...though managed to get it back after 2 days of tension, though not fully as some third party apps data didn't load properly).

I was so relieved to find this post and know I am not the only one having these problems. I too have been trouble shooting on my iPhone 6 with a senior tech specialist to fix all these same issues with apps not downloading, streaming music not working, iCloud not backing up, links not opening in email, not being able to purchase music thru iTunes and to sum it up he has no idea how to fix this problem. He is waiting to hear from whoever else is looking at the issue from our notes during our trouble shooting. It's been 3 weeks:( My old iPhone that I use as an iPod now works perfectly fine but still has iOS 8.4. I am definitely not updating that it's the only device I have besides my laptop that I can listen to Pandora and Apple Music. Other than that I've been stuck listening to YouTube playlist on my phone. i might just go back to my iPhone 5 if techs at Apple can't even figure this issue out.

Good luck.

The problem has been resolved from back end (it did turn out to be server side issue). Please check.

All things are working now. *touch wood*
