Can someone please check and see if they also have the following issue:
In Screen Time > Content and Privacy Restrictions > Privacy, I cannot set privacy selections (Allow/Don't Allow) for Photos or Calendars (other items work fine). The setting selection within those two items always reverts to "Don't Allow Changes", while the status remains at "Allow" on the privacy restrictions main list (functionally changes are being allowed). The Photos and Calendars items seem to be stuck in "Allow" mode despite a
"Don't Allow Changes" selection appearing within each.
This occurs whether or not a restrictions password is set. When a restrictions password is active, attempting to change the Allow / Don't Allow selection for calendars or photos also does not invoke the restrictions password prompt (it should).
I have it on both my iPhones, a 15 PM and a 13 Pro, running iOS 26 B2.
