Breakout rooms and external attendees

we have colleagues who use Teams to run external training/awareness sessions, these are mainly with external attendees and around 40/50 per session.

Everything used to work fine until August 2024, but since then, there have been majors issues.

The attendees are all using the latest version of desktop teams. the issues are:

Some attendees come in as assigned attendees, others come in fine with name.
When screen sharing for example slides, the ones who are unassigned cant see anything
When trying to put them into breakout, some go in, others cannot and they have to remain in main room.

As ive said, there this was all working perfectly prior to August 2024, when i believe there was some major upgrade to teams.

any help please?
