I’m also having problems, but I’m not sure the extent to which it’s affecting me as you can never know what messages you aren’t receiving… I am successfully using open bubbles for iMessage on my MK and the group text function has worked correctly for me a handful of times…. But I do have one group text that predates my MK that I can’t receive ANY messages to my MK. This group is a mix of iPhone and android users. I disabled RCS on my iPhone prior to switching, and I’ve verified my phone number on the google form to turn off RCS. If the other participants message the group I never receive the messages, and I even tried starting a new group from my MK where they received my message but no replies came to me. One of them also tried to remove me, and then re-add me. I additionally tried to make a new group chat with a different sim/different number which has never been used for RCS as far as I know, and they received that message but I received no replies. I know at least once on another group text I had missing messages, but that was before I submitted my number to be removed from RCS. Is this an RCS registration issue? Or is something else going on? I really miss this group message and I have major FOMO about what other messages I could be missing. I use US mobile with a t-mobile sim as my primary, and I have stellar coverage usually full bars in all my typical locations. The other sim I tried was us mobile Verizon, but it had the same problem. Open bubbles is working fine for my non-android communication, so I don’t think that is the issue either.
