I back my iPhone 6 up to my macBook Pro once a week and make sure it's backed up in iCloud by plugging it in every night on lock screen. Ever since the new up date iTunes says my iPhone 6 has never been backed up to iCloud and this morning my iPhone 6 screen had a pop up that said the phone has not been backed up for 54 weeks. When I go to settings> my account> devices all of my devices ( macBook Pro, iPad Air, and iPhone 6 ) appears in iCloud. Anyone else having this problem? If so were you able to rectify the problem.
