Note 20 Ultra 5G not downloading MMS.

Same, i have the same phone and it started the same time for me too.  My group chats come as individual texts with the download symbol now. Sms and rcs seem to still work just mms that's messed up

Same thing, All the Note 20's in my house.  Cleared cache, tried a different app, same result. 

OK. So after trying multiple suggestions I fixed it by going to Settings- Connections- Mobile Networks- Access Point Names- Add (upper right corner). When given the option to edit, type in; Name: ATT Nxtgenphone APN: NXTGENPHONE (All caps). Then the only other change is in the field for APN type: default,supl,mms,hipri. Make sure your 2g capability and international roam 2g are enables as well. Worked immediately for me.
