Participants not seeing PowerPoint slides advance in Whiteboard

[LBPC]

Hi, 

I inserted a PowerPoint slide deck into Whiteboard so participants could see a presentation while also viewing our meeting notes. I'm able to advance the slides on my end, but the meeting participants don't see the slides advancing (it's stuck on the first slide). Participants can manually advance the slides, but as the presenter, I want to control that. Is there a way for the host to advance slides for all participants?
