Wd mycloud 3tb

I have just installed on my home network my new mycloud 3tb. For the moment I have used the automatic installation. It works well but it is difficut to upload my photos fron my android phone with the specific app.

With my galaxy nexus the upload works with difiicultes  but with my galaxy s4 it is impossible to upload photos both automatic and manual.

Please help me.


Are both devices running the same version of the app?

Also, are both devices running the same android version?
