I'm on 1.25011.56.0, where Phone Link says it's the latest release, and that hasn't fixed the issue.
Hi Esben. I also have 1.25011.56.0 and it is working fine for me. My Win11 is version 24H2 build 26100.3194. Not sure what yours is doing. Are you replying to the clean version of a given recipient? I still see the 2-person group chats there, but when I send a message directly to the real recipient (non-grouped) it doesn't end up back in the group one as seen previously.
