There are several issues when adding a video library on a page in the new builder. When looking at the site on the desktop, the video library extends over the right edge of the browser window and you need to scroll horizontally to see the full library, it doesn't do that in the old builder. When looking at the site on the desktop or the mobile phone the "load more" is missing. So you see only the first few videos of the library but you can't load more. Loading time on the mobile phone is slow, even though I have 450Mbps Internet connection. The page with my video library built with the old builder loads much faster. And I'm not sure if is the new builder, but I had Chrome (on Macbook) get stuck twice today while I had the new builder open in a tab. Not sure if it cause the problems, but I'll keep an eye on it. Thank you for working hard to making things better for us users! Rita
