OK - this is not the first time you’ve posted about this, so I’m going to ask.
What is the problem with the video embeds? So they are now framed in a bigger black square - but the videos themselves are in the correct aspect ratio, so I am not at all clear what it is you would like fixed. The new presentation format has the benefit that if your cursor goes over the video the time/progress line and the titles are still shown but do not obscure the video itself. I think it’s an improvement.
And if you want to attract the attention of someone at BB it helps to @ them. They’re not necessarily reading all this stuff, you know.
