Waiting Room Video Doesn't Always Work

Hi All,

I have added a video to the waiting room for all users, and it has been working fine up until now.

The hosts in Australia have reported that they just see a black box but still hear the audio.

It's happening on mobile, desktop, with and without the app installed.

Everything is switched on as it should be.

The only thing I can think of is the participants' internet connections aren't good enough to load the video content?

Any ideas?
