Cannot send/receive MMS since phone upgrade
I have had Xfinity Mobile as my provider for about a year. When I signed up, I was using an LG X Charge, and using Textra as my messaging app. When at work or at home, I would have cellular data turned off, and could always send/receive MMS messages effortlessly when at work or at home on wi-fi.
A couple of weeks ago I upgrade to the "better" Motorola g7 Power. Since then, when on wi-fi, I get errors that I cannot receive MMS messages when I'm on wi-fi. I almost always have to turn cellular data on to get them. This is on the same wi-fi connections, which are both fast (especially my home connection). I also believe my phone settings to be correct (the Xfinity Mobile APN was in since the start).
Other than what might be stock on this phone vs. my last one, I have nothing different installed on this phone. I am looking for help into why my MMS messages seem to be blocked. Thank you.
