Rhiannamae: So glad this isn’t just me! Endless loop of logging into your Apple ID. Unable to buy apps and lost all music purchased from iTunes ad I cannot log into my iCloud. Just update IOS 11.1 in hopes of fixing my problem but no use. If any one finds a solution to this problem then it would be very useful!
