So, Google resolved the interop issue with "liked an image" and similar reactions back in 2020. I can't remember that being an issue for years with reasonably modern Android phones.

Yeah, I've had some isues in the past with pixelated videos but again, almost zero in the past few years. But there are ten billion better places to post videos than via group chats, especially to conserve memory on people's devices, and pretty much everyone knows it at this point. Literally everyone I know has been posting videos via Youtube or Facebook or Instagram or Whatsapp or Discord or Slack or Google Drive or Dropbox for years at this point.

But yes, Apple should absolutely support RCS for encrypted messaging in group chats with other devices. 100% with you on that one.
