Local sync from iPhone pics to EX2 not working

Hello,
I’m using my EX2 as a local backup for my iPhone 6 pictures. The backup process used to work fine but it is now NOT transferring the actual files. It’s just making the backup folder, then claiming “success”, but the new backup folder is empty.

I don’t want to use the cloud backup feature; I’m happy just having a local backup of my original photo/video files. I let google photos make cloud backups and just want the EX2 to hold the original quality files.

Any ideas? I tried changing the folder naming scheme and it always successfully creates the correct folder name; but the folder is always empty and the backup process claims it worked…but it did not.

Here are some KB articles that may help:

Sorry but those links did not help. I’m not using MyCloud or any WD app on my phone. This is just a plain iPhone 6 being plugged into the back of my NAS with a USB cable. It used to work just fine, identifying and moving my pictures off the phone and into a folder on the NAS.

Should that functionality still work or not?

I gave up and just installed the MyCloud app, which seems to work just fine. I’m assuming something in iOS doesn’t want the pictures accessed directly any more, so I’ll use the app to do backups from now on.
