Have done the steps - apps do not show up in "apps that want to access my calendar". Why not?

[wpearson8]

Cannot give access to apps to add events to my calendar.

Also cannot give google access to my photos - so cannot save photos or clip art to my iPhone 6s Plus.

Apps do not appear in settings ...privacy
