I can’t use FaceTime
I can’t use FaceTime from the very first day of getting my iPhone 11. In FaceTime I got an pop up saying “ your iPhone must be signed in with same Apple ID for FaceTime and iCloud” but actually I signed in using same Apple ID, only I didn’t add any email address because my email ID is invalid. I also receive the same pop up in iPad Pro and iPad mini.
