I have usually disabled “Edit” mode for the notes tab to have more screen space. Unfortunately, scrolling does no longer work in “Read Only” mode for me.
In “Edit” mode I see the scrollbar and can scroll the notes area, when I switch to “Read Only” mode I still see a scrollbar (size slightly adapted), but scrolling does not work - neither with the scrollbar nor with the mouse wheel.
Don’t need this very often, most notes are lead sheets designed to fit on the screen without scrolling, but on some notes I have additional reference material at the bottom like scans of sheet music etc.
