Uploading photos from IPad

I have both WD photos and WD2go on my IPad 2 but I still cannot find how to upload photos from my iPad to my WD live Duo NAS. My son has WD2go on his android tablet and it works fine for him.
Any advice on how to get this to work on my iPad?

Next to the name of your NAS that you’ve got on WD Photos, there’s a little button.

Click that to upload photos.


Thanks! So simple yet …anyway it works now, I wonder why the app needs my location in order to work?
