You can see an example here:
https://www.investopedia.com/terms/r/returnoninvestment.asp
The video player should appear immediately above the "How To Calculate Return On Investment (ROI)" title. We do run pre-roll advertisements on the video player, so I'm sure that's why it is being flagged and removed.
Not sure if that's something you can (or want) to fix, but I thought I'd flag it anyway because we've had a number of users email in about it.
Thanks
