Broadcast messages and breakout rooms

[lp118]

We have just recently noticed that Broadcast Messages which are sent to all Breakout Rooms are also being seen by people still in the main meeting area, which we didn't think was supposed to happen (and I'm sure it didn't some time ago). Please can you advise whether this is expected behaviour, and if there is a way to communicate with just all the breakout rooms without the other participants in the meeting seeing the message.

We use the breakout rooms for individual interviews while retaining other candidates in the main meeting area. We use the broadcast messages to communicate with the interviewers between candidates so that they know what's coming next. There is no requirement for the candidates to see these messages, and essentially we would prefer that they don't see them (just in case there's any issues with a candidate).

Equally, it doesn't help that the broadcast messages only stay on screen for a few seconds - are there any improvements planned to extend this viewing time?

Thanks for any help you can offer
