Since a couple of days internet connected applications (such as facebook) have stopped working on my wife's iPad mini which has iOS 7.1.2.
- internet works in Safari
- internet doesn't work in Facebook (though it works with the messenger component), the app store, Dropbox
- trying to install updates fails (seems to time out, doesn't even start downloading)
- tried to sign out from the Apple account (Settings -> iTunes & App store) and sign back in, however it won't let me sign in (tried multiple times and confirmed that the account details are correct by signing in on a PC)
- tried rebooting multiple times to no avail
Any ideas what could be done? I will try to connect it to a PC having iTunes later to see if can help – also will try to update it to iOS 8.4 (hopefully it's possible to do so without being signed in to the apple account).
