It looks like Chrome, Edge, and IE had an update and it is messing with YouTube embedded videos. Flash is being phased out which is affecting the videos.
We are currently working on a fix for this to see if there is a way around it.
FireFox seems to have not been hit with the issue yet (as they phased out Flash a while ago) and we hope to find a resolution soon.
We will keep you updated as the information becomes available.
