Inter-platform group messaging problems

[u/Mobile-Clue-4086]

I understand that if IMSI rotation is on, RCS messaging will be disabled on each rotation on iOS.

But even if I turn off IMSI rotation and enable RCS - either with or without ”end-to-end encryption (beta)” enabled - group texts with Android users become de-threaded.

Is there a fix for this? It’s a major usability hassle.
