I assume this was an MMS group chat? Did you add yourself to the participants list manually?

Any additional info would help as I can't test MMS messages.

[Quackdoc]

No, I did not add myself, and yes, this is an MMS group chat, created I believe by another phone via Google messages, perhaps RCS? not sure if RCS stuff is related.

Do you have any other messaging apps (e.g., QUIK)? Could you check if this problem also exists there?

[Quackdoc]

It doesn't seem like it, though I did find out if I respond to the old group chat I don't receive my own messages, only when I respond to the new created group chat, but all incoming messages go to that new group chat.

So on this I reply to the top one. And I receive in the bottom one. If I reply to the bottom one, I received my own message.

EDIT2: Quik does have the same issue actually

[naveensingh]

While this appears to be a change on Google's side, I don't see any reason why the app should not exclude "self" from the participants list when sending group messages.
