Hey @rogermedia,
You said you’re using the Youtube Embed method but after checking the page you have not changed, your setup is you inserted the Youtube URL in a Video Player element. That is not embedding. Even if that might have worked in the past, it’s not guaranteed to work continuously because the setup is incorrect.

I’m sorry to say that your setup from the beginning is incorrect. The Video Player element will only work for self-hosted videos or direct to video URLs like https://example.com/video.mp4
. That is what the label, VIDEO SRC URL, says.
I understand this is tedious and frustrating but, there is no way to convert your current setup to the Embedded Video Type. You would really need to convert all your video setup manually to use either the Video Element (Embed Type). Or, use the Classic Embedded Video Element.

If using the Video element (you already know this but I’m just confirming), you need to select the Embed Video Type.

That’s the same setup if you’ll use the Classic Embedded Video Element.

If you mean that you’re using the Classic Embedded Video element then all of the sudden it changed to the Classic Video Player element, that is impossible and there’s no such change in our theme for that.
Hope that explains it and thank you for understanding.
