Background App Refresh grayed out
I have an iPhone 6S Plus running iOS 12 and my Background App Refresh menu under Settings/General/Background App Refresh is grayed out. The "top" setting for Background App Refresh is turned on and I can see a list of apps that have Background App Refresh turned on or off but NONE of the settings on this screen are accessible.
On one older post with the same issue the poster was told to check Settings/General/Restrictions to check a setting however I have no such Restrictions folder in that location or anywhere else I can find. FWIW this is a privately owned phone (non business) I purchased new from Apple.
Any ideas on how to gain access to my Background App Refresh settings?
