Video Lightbox

So, I sort of got this to work with this solution: https://kriesi.at/support/profile/msutherin/replies/

However, it only works sometimes. I took down the button on the desktop version but kept it on the mobile version. Basically, I want to have the button clicked and the video to play in a pop-up lightbox. It doesn’t seem to work on mobile and instead just links to the about page.

I have this as the link:

And the link to the page below, but please view in mobile.

I need it to work all the time. I’ve tried on safari, chrome on both mac and pc, and also on mobile (ios) and I get the same results. I’d say it works about half the time.

It feels like it just times out and gives up if the video doesn;t play right away.

I added this:

?iframe=true

at the end of the video link. It works sometimes. Like 1 out of 10 times.
