iPhone Cellular Data Settings Not Saving
The Cellular Data settings menu lets me check/uncheck the apps I want to use, but as soon as I leave Settings whatever I checked/unchecked reverts back.
If I try to use one of the apps, I get a notification "Cellular Data not turned on for this app", even though I had checked it.
It seems like the settings are frozen or something. My iPhone did update to iOS 12.3.1 so that might have something to do with it.
I tried resetting the Network Settings, but the same error occurred. I never had Restrictions on or anything like that.
Any advice is appreciated!
