There's a lot to like about @matrix , but I just tried to DM someone and it took several hours(!) before they 'joined' the 'DM room' and I could start writing... yeah there's some way to go. (we were both using :matrix.org accounts)
@raboof huh that delay in joining is waiting for them to accept the invite? and you can already send messages that they'll see after accepting
@raboof technically it depends on the rooms' "who can read history" settings, but with a DM that's automatically set in the proper way for that ux
@f0x https://github.com/matrix-org/matrix-react-sdk/pull/7998/files - though I see there's some ceremony to complete before this PR meets all requirements... something for later ;)
@f0x so after accepting the invitation, those joining the conversation will be able to see all messages exchanged before they joined? Or only those written after the invitation was sent?
