Video in engage interaction will not play automatically from web-link only

Joe (or anyone) can I get your help with one more thing on this?

I decided if it was a choice between a bloated file with inserted videos versus a slim file with embedded video links that don't autoplay, I chose the latter.  I spent hours rebuilding this now my file has all embedded links and when I display them on chrome, all I have to do is click the play button.... not what I wanted but not the end of the world.

NOW THERE'S ANOTHER PROBLEM and that is when I tried to play the engage file on a mobile device I get audio-only no video.

Try looking at this on a mobile device -- no video (for me at least) https://tdgstoryline.s3.us-west-1.amazonaws.com/ERG_2020+-+Engage+output/interaction.html any ideas? 

Help! This is driving me nuts.  I have articulate 360 and using Engage.
