main chat, broadcast messages and breakout rooms

I hosted a large meeting yesterday and had instructions with a link to share with the 16 breakout rooms.  The broadcast message doesn't make links live to be clicked, and the Main chat is apparently cleared when the participant enters a breakout room, so they cannot reference the main chat.  This made starting off the groups AND facilitating the breakout very difficult and I ended up sending "Teams"  messages with the instructions and links separately to all of the team leaders in each breakout room. I feel like this needs to be fixed quickly or the breakout rooms will continue to not function well if there is any detail that needs to be shared.
