I noticed today that in the iPad app scrolling, just of the main content area, does not work with a connected bluetooth mouse for some reason. It worked with a connected touchpad (or by touching the screen directly obviously) but my mouse did not scroll. The scrolling works in other apps, or even interestingly enough, the sidebar of Logseq, so it’s just the main content area that has the problem.
Specifically I was using this mouse Logitech MX ERGO Advanced Wireless Trackball Mouse - Canada but I’d guess the issue should be reproducible with any bluetooth mouse that has a regular scroll wheel rather than a touch surface.
