Hi,

Much too often the undo arrow becomes grayed out in the middle of making annotations. After the first undo the arrow stays grey and I can't undo anymore so I have to cancel and start over annotating. 
Also sometimes the stylus becomes unresponsive and it takes a few seconds for the scribble or note to appear or the two or three characters or scribble attempts show up all at once like if the system is thinking or choking ...
I have a brand new Onyx Boox Max 3,  I work on normal refresh mode (default) and no other apps are running ...


Any ideas?  I'm worried whether there's something wrong with the tablet ... every other app works fine.
