I did a pdf export yesterday for one note. It went well, although seemed to be a bit slow. I want to try with several notes, today, but haven't had success to see if it works the way I think it should. I have worked more on this today and I am not especially pleased with what I am seeing. My jpg files that I export as pdf's come through fine. A pdf note that I have when exported just gives me an unclickable link rather than the note saved as a pdf. Maybe I am just not understanding.
I then went to another pdf note, which I tried to do a pdf export and it did not work. However, when I right clicked on it and clicked Save as, it did what I needed to have done. It appears to the inexperienced me that I can export jpg to pdf, but when it comes to a pdf note, I just need to do a save as rather than export it.
