I don't see anywhere you said you opened an issue.
② It is backlash or hysteresis.
•In the Audio section, view a lot of tracks with TRACKS.
•Swipe up so the top pane goes away.
•Use the scroll bar to go down to the Ms.
•If you use the scroll bar to scroll up until the top pane reappears, you are transported a long way back in the list! Presumably, the same finger position is now a different percentage down of the run of the scroll bar.
•Down with controls that have a mind of their own!
