iOS 8.4 - Can't open App Store, iTunes, iBooks and Music apps
I've used iOS 8.4 since its release and was fine until several days ago, when some Apple apps that have a store component (App Store, iTunes, iBooks and Music) crash almost immediately upon launching. No other apps on my iPad (including iTunes U and Podcasts) have such issue.
I tried restarting my iPad several times (either turning it off the normal way or holding both the Home button and the sleep/wake button) but that didn't fix this issue. I also logged out of my Apple account, and logged in again - no luck here, either.
Anyone has any idea what the issue might be, and how it could be fixed?
Thanks in advance,
Moh
