My galaxy S22 won't download MMS messages or send them. I do have a solid mobile data connection as I can quickly load from various social media apps, and view the internet. I have tried this with Wifi on and off. I have reset the phone, reset network settings, cleared the message cache, tried switching to a different default messaging app, toggled auto download on and off. Nothing has worked. In the past, there have always been occaisional MMS messages, both incoming and outgoing, that would get lost in space when interacting with an Iphone user, but this is different. My phone knows the messages are there, it just will not download them.
