"Encrypt iPhone Backup" greyed out
Hi. I'm unable to access the "encrypt iphone backup" check box in itunes. I've seen responses that suggest deleting profiles on the iphone but i don't see any profiles in my settings. There is a Per-App VPN set up for work (iron mobile). Speaking of which, when I installed mobile iron I was forced to download a profile but I don't see any "profile" menu in my settings -> general.
iPhone 6 Plus, iOS 10.3.3
