Is anyone else having an issue with their iPhone XsMax using excessive cellular data, and not showing wifi connection icon on home screen, but shows it on the WiFi settings page? I went over my cellular data last month. And noticed when i should have been on wifi, the phone wasn't showing icon. I went to wifi settings and shows the correct SSID but not using it. Apple store said phone passed all tests and that i should reload OS from computer to "Fix" it, so reset phone and now its seems to be doing it again.
