I noticed the following behaviour and consider it a bug. How to proceed?
When I open a new note in the iOS notes app (ipad pro 2020) and I open the drawing tools  and I start to draw with the Pencil then the drawing tools stay open (as expected).
When I close the drawing tools  and reopen them  and I continue drawing with the Pencil then the drawing tools minimise as if the "Auto-minimise" option was active (but it is not).
This prevents e.g. the usage of the ruler tool (it disapears with the drawing tools).
Any idea how to appproach this? Can I file a bug report to Apple? Worth it?
