Restoring iPhone from iCloud backup
Hello,
Just bought the new iPhone XS and chose the option of restoring the backup of my previous iPhone 7 plus. It seems that every thing was indeed transferred to my new phone, but 24 hours has passed and whenever i want to upgrade the software to iOS 12 I still receive a message saying that "You can install this update when your iPhone is finished restoring from iCloud backup". I am sure my hone is already restored and I don't know how to continue. Thank you!
iOS 11.4.1
