PowerPoint Live Embedded streaming video do not play on some viewers

Occasional Visitor

I used PowerPoint live for the first time yesterday to share Vimeo videos embedded into a Powerpoint presentation.   The video did not play for 2/9 guests (outside our company).  Any suggestions on possible root cause is appreciated.   Thanks in advance.

We've heard reports of that happening but I do not have a solution to offer at this time. Anyone else?
Well, current implementation of PowerPoint Live does not guarantee you are going to have a 100 % fidelity compared to the original PowerPoint presentation. Also having different behaviors depending on the attendee is not so uncommon in my experience and there is not way to know why this happens
