Raising that when you pin a certain number collection to your sidebar that extend past the viewport, there is no option to scroll. Unless you have a larger screen, they’re just lost below the fold.
This should be updated so when the window is resized or collections extend past the viewport, you get a scroll option so you can still access your pinned collections.
Hey@Devin Luby thanks for bringing this up. We have pushed a fix and this should be working properly now. Please let me know if are still experiencing any issues with the experience. You might need to refresh!
