WD Photos won't display photos

I’m on an iPad.  I’ve installed WD2go and WD Photos.  WD2go works just fine, I can see the entire folder structure and see each of the individual photos.  WD Photos seems to only see some of the folders.  The folders is does see, it shows a few thumbnails but the other photos are missing.  Even if I click on a thumbnail that exists it tells me “File not found (404 17.26)”. The public shared picture folder I created on my PC contains over 10,000 photos.  Any ideas on why WD Photos won’t display the pictures?


Are all the pictures JPG/JPEG ONLY?
