Figma Buzz grid view can't scroll to the bottom, last asset groups unreachable (60+ groups)

We've been using Figma Buzz actively since the beta (about 1.5 years). One of our files now has a large number of assets and more than 60 asset groups (or rows).

Problem:
In grid view, we can't scroll to the bottom of the canvas. The view stops at a certain point, so the last asset group(s) can't be reached. The assets in those groups are only visible in asset view.

It looks like there might be a maximum canvas height or scroll limit in grid view.

We work in grid view most of the time because it's much easier for preparing carousel posts. As a workaround we're splitting the assets into two files, which isn't ideal.
