Facetime does not show up in Settings > "Cellular" and it says I cannot Facetime without WiFi
My iPhone 11 does not let me Facetime without Wifi. When I go to Settings > Cellular to turn on cellular for the Facetime app, it does not appear where all of the other apps are listed.
If someone Facetimes me when I do not have Wifi, I never get a Missed Call notification, but their phone says they called.
How can I set up Facetime with Cellular data?
iPhone 11, iOS 14
