I don’t have a solution but just thought I would let you know I have a similar problem with my new drive connected through my network. I am using a Mac. MyCloud drive shows up but when I click on it nothing happens!!!
I’m running into a similar issue as well. I’m just using the app have both drives plugged into my home network and the upload fails at some point and you have to start over. It least that has been my experience so far.
Did anyone get any other response to this problem? I’ve just found the Network Import tool and getting a similar issue in that nothing happens when I click on MyCloud drive, no shares are shown, so it’s not a very helpful tool
