Cannot scroll down pages in design mode

When I go to edit my web pages, I see a scroll bar that on the right side of the content page where I should be able to scroll down to see the rest of the page, but it’s greyed out and doesn’t work. I can only see the part of the design page in the main screen. Please advise. Using a Macbook Pro and Chrome (regular and incognito), have also tried Firefox to no avail.

Please advise. TY

Hi Tracie, would you mind updating your post with a new read-only link? It doesn’t seem to be valid. Instructions are here. Thanks!

Thanks, Tracie. I seem to be able to scroll just fine on your project. Would you mind taking a quick couple of screenshots, or even better a Loom video and show me what’s going on? Thanks!

Hi! don’t click on the scrollbar on the right, instead, do a two-finger vertical scroll on your trackpad -without clicking anything. Hope this was helpful!
