Updated Firmware - Neoreader won't export pfd to "storage/note" folder anymore

Just updated the firmware on my Max Lumi. Now when I got to export a pdf with changes to "storage/note" or to the source file, it says "failed to export".  

I transfer documents using Dropbox. Make changes to pdf's in Neoreader, then export to "storage/note" then I use dropbox to share the document with my desktop.

Any adjustment or changes to settings that I can make?
