I'm about to move from an iPhone 6S to an 8 or 8 plus in a couple of weeks.
I'm using the iCloud for my back up. But, I opnly see some of my apps listed with regard to back up when I look at settings and iCllllllloud on the phone.
Currently 2 gigs of the 5 gigs or about 40% are used.
I know I have a lot more apps than are listed in iCloud settings on the phone.
How do I make sure that all of them get backed up before I upgrade?
