Live events in Teams preview error when producing event

Hi,

I had this today.

I was the only Producer and had 16 presenters. Initially the Live Event screen was working fine.

I then noticed someone had messaged me in Chat so switched away to that, it was someone requesting the link so I sent it to them. I then switched back to the Producer view and the Live screen was no longer working.

I know that when over 9 or 10 presenters I don't see their video feed. That's fine. I could see most people in the preview and when they were queued up to go live next. It's just the live screen that showed nothing other than "Preview is unavailable" for the rest of the event. Even when I shared a Powerpoint presentation, that wasn't in the liv side of the screen.

All participants saw the feed properly, it was just me as the Producer that couldn't actually see what I was putting out there. It's very unnerving.

This isn't the first time I've had this problem. I'd love some official feedback or a fix.
