I have no doubt this is something I've done wrong, or a setting I've clicked on, but whatever it is, I can't find the solution. I use the FreePrints Photobooks app each month to create books from our vacation memories. I store all my photos on Dropbox in named folders and I can access them all through the FreePrints app - except for the folder with all our holiday (vacation) photos. It appears to open but no content (sub folders) show up. It means I have to export the photos I want to my device before using the photobooks app, which is very inconvenient and time consuming.
Any suggestions please?
