Out of nowhere, I can’t send or receive texts in group chats with non iPhone users. I can text them just fine individually though.

I have an iPhone 12, and I’m in a group chat with two Samsung galaxy users. We chat in there constantly, but all the sudden I’m not receiving any of the messages for that group. When I try to text, it always just says “not delivered”.

I can text these people individually with no issues. It’s the group chat that seems to be the problem. I’ve tried some troubleshooting, including:

ensuring mms, sms are enabled

turning it off and on again

resetting network settings

updating phone

deleting the group chat and making a new one

can anyone help me with this? My cellular provider is t mobile.
