There are 2 issues I am having with Goodnotes when using the Slim Pen 2:

1. The pen has an eraser on the back, so when I turn my pen around to erase and then turn it back around to continue writing, the tool doesn't automatically switch from the eraser to the pen again. This was initially working, but it no longer works in the latest version.

2. The pen supports haptic feedback, so whenever I write or draw with the pen, I get haptic feedback from the pen. Most other writing programs I use with the pen support this functionality. This used to work in the first beta build of GoodNotes that I downloaded, but it has stopped working since then.
