Samsung s21-5G. I am outside the country. WiFi calling and and individual messages from one sender come in just fine. Group texts will just not download. Usually I can see a message is there and it says tap to download but if you tap I just spins and never downloads.
Usually if I restart the phone entirely it will load the messsages so I think I have all the settings correct to do this but it only seems to work the moments after full restart.
