Apple pen with pixel brushes and other brushes

I am using a new 2020 iPad Pro and Apple Pencil. When I select many of the pixel brushes, especially the comics brushes, my Apple Pen shows no response. I can change the pressure or velocity settings for the pen on the brush menu, but the response is still nil. I can get the crosshatch pen to show, but the response is spotty; there are some blank spaces that the pen cannot draw on(?). My finger can be used to draw easily. 

Additionally, the pen size for non-pixel brushes is radically different between my pen and my finger, the radius difference is almost a factor of 10! It's impossible to draw a very thick line with my Apple Pen. 

Am I missing a setting, or is this intended behavior? I have re-paired my Apple pen and restarted and reinstalled Fresco to no avail. Sketch works perfectly, why does Fresco not?

I have included an image of the crosshatch brush with my Apple pen. I drew a scribble for 10 seconds, note the lighter space in the middle. I ran the pen over that spot multiple times with no ink added to the image.
