Our team ran into what seems to be a pretty annoying bug with the timeline view.
After a while if you keep on scrolling up/down, eventually the sidebar where it shows how things are grouped by completely disappears. To me this feels like a bug where whatever is suppose to trigger redrawing it hasn't been fired. To fix it you have to scroll again to force it to redraw, though sometimes it also still disappears. Another way to force it to redraw is to resize the splitter.
I managed to replicate it in a new Base with a very simple table (see attached gif). Although it doesn't look so bad in this example, in our actual Base this can be incredibly frustrating as it's happening frequently enough, hurting Airtable's ux.
