WD Photos Iphone App - Doesn't find all my photo foldes

WD 2go pro works flawlessly.  I can see and access all my photos.  But on WD Photo it only shows 13 picture folders of hte 100 folders I have on the My Book Live drive.  I’ve uninstalled and reinstalled the app.  No change.  Any ideas?

Thank you

Do you have all the photos on the public or share pictures folder for the MBL ? 

Move the content to the share folder
