I have this exact problem also. Talked with AT&T yesterday and did the troubleshooting to no avail. 

Items tried: rebooting, reset network settings, turn off wifi, cleared device cache, cleared messaging app cache, confirmed APN settings, AT&T sent new provisioning

Samsung Note 20 Ultra unlocked, firmware ending in UCB which was installed on 4/13 and all MMS capability ended.

"were you texting with iPhone users? or Android users? which carrier do they use?"

Hi ,@beyondplt  Yes a mixture of Android and iPhone users. A lot of them use AT&T. I don't know what everyone of them use. 

This is not a cross network or cross device issue. Unable to send or receive MMS from my wife's phone which is a unlocked Samsung S20 Ultra and on the same AT&T account.  She can send/receive MMS just fine from anyone else. 

The issue is between my phone and the MMS gateway. If I try to send anything MMS (picture, gif, multiple people) it gets stuck "sending" and never completes. If someone sends me a MMS, I get a "there's a new MMS click to download". I click, the icon spins, and it never downloads.

@beyondplt same as the other poster, unlocked note 20 ultra, group and single mms with Android and iPhone users with either AT&T or Verizon. My husband has no issues with the exact same phone.
