After upgrading to ios8 iCloud won't recognise password on iPhone and iPad only on my Mac Mini and Macbook Air
After upgrading to ios8 my iPad and iPhone could not sign in to iCloud. The error was either 'server error' or verification failed. I reset the password and verified I could log in via my Mac Mini and Macbook Air but I still get the error on my two iPads and iPhone that verification failed.
iPhone 5s, iOS 8
