I uploaded three videos to Youtube.
The first video is showing how the notes appear using 3 of my own separate PDF files.
The second video is of the file you sent me. As you can see, it appears to have the same issues.
The third video is opening an ePUB file for comparison - you can see that ePUBS look fine.
I notice that when I open a PDF some notes appear on the first page. Sometimes ALL the notes from throughout the book appear crammed on the first page. Also, it doesn’t seem to affect footnotes that are embedded in the file. You will see that in these videos. In the second video (using the file you shared) one of my notes (the last one I added) does appear sporadically but it appears on the previous page, not on its proper page.
Anyone else experiencing this?
