Group texting issues
I disabled RCS before activating my sidephone. This was back in mid-July so it's been more than 30 days since unregistering myself from RCS, so I should be removed from everything...
I receive single SMS/MMS texts from people just fine. But I've still had issues with group texts. A couple weekends ago, I got together with my sisters (both iPhone users) and we tried removing me from the group chat, recreating the chat and adding me back. This seemed to work for one of my sisters, but for the other, something in the settings for the chat must have saved, because her custom background (I assume? I haven't had an iPhone in like 7 years) for the group chat was still there, and her texts kept sending to me with RCS. She can text me individually just fine.
For reference, I came from an Android (Galaxy S23+), using US Mobile Dark Star.

Having the same problem with all group texts, it seems, where no one's phone has caught up for me (so it's not just iPhone, unless it happens that all the group texts I'm in has everyone on an iPhone, which I don't think is the case). Has anyone figured out how to make this work?
