Messenger not working without wifi
recently we transferred our phone from an iPhone 6s+ to an iPhone12. For some reason we can’t use messenger unless we are connected to wifi. In The past we have always used data. We have tried all the helpful suggestions online (rebooting phone, starting & stopping airplane mode), the refresh suggestion, checking to be sure data is checked for both Facebook & messenger. Facebook will open without wifi but not messenger. Any suggestions? Thank you!
