Cant access all my picture files on Iphone WD Photos app

So last night before bed, I repeated step 1.
Disable remote connection, reboot drive. Re-enable remote connection. Checked this morning.
I now only have 71 photos.

Therefore:
My cloud app - all pictures
WD photos app - 71 pictures
PC connection - all pictures

Do I have a problem with my drive or is it an app issue…???
