When joining a meeting for the first time the video does not show. It is only after the user touches the video share twice (once to turn off once to turn back on) video can be viewed on device. This work around seems to also work when touching mute twice.
4.1.30420.0817 is what I am working with but I have tried all versions 4.1.30420.0817 and above. I did notice in the most recent version I can see video from the device in the bottom left without any issues on first call but not the other participant.
