Hi theducks and stumped,
Thank you so much for your advice. After lots of trial and error, I think I've zeroed in on the issue as a paths issue as you suggested. The pathfiles are identical both in name, in locations, in Moon recent lists etc, so I went to see where each dropbox notification was taking me after each time I closed a book.
Stumped, I went into the dropbox/apps/books/moon+/cache folder and as you say, there are, annoyingly, 2 x files being generated for each book, however the difference isn't in the names but with each book having 1 x file ending in .epub.po (the tablet) and the other ending in .epun.an (the phone). They are now correctly saving next to each other but, for some reason, this slight difference in epub format (?) is making them miss each other consistently which I'm guessing is the source of the issue. Is there any way this can be fixed?
