What I did: Running Agenda 9.0 in split screen (landscape) with 2/3 of the screen. Asana running in remaining 1/3. On iPad OS 13.3 (beta).
What happened: Tried to drag the left sidebar with projects to the left to hide it. The sidebar will not hide. It will become narrow, but it will not go off screen. Even if drag the sidebar handle all the way, it always springs back. Same goes for calendar
What I expected: The side bar to go offscreen, maximizing the space i have to view my notes and calendar[
Things that might be helpful to know (Agenda version, OS and model, etc):
