I don't have that bug (build 3.2_0ae74d7d5d
, note air 2). The converted pdfs open and perform flawless with neoreader.
Also I haven't experienced any problem exporting notes via pdf to my desktop but I have severe performance issues with the pdfs with Foxit. I can not even scroll because the lag is so extreme. Seems to be a Foxit problem. Open onyx note pdfs via firefox or edge works fine. The notes don't have any layers nor are the pdfs large (yet). I probably have to look for an alternative pdf reader on my Win10 desktop (it's a midrange gaming rig, so it is certainly not a hardware issue).
All in all I've experienced some weird not reproducible behaviour with the notes app on note air 2 like severe lag while note taking, some parts of the screen not reacting to pen input and weird screen flickering. Those problems appear very rarely and disapear when I reload the note.
The current state of software and firmware with 3.2 certainly needs further stability work...
