If you are talking about setup and the bottom option Send data to WDLiveApp, I have it set to YES.
I cannot see any mention of wdsendtether.
I can run this manually of course but I don’t think that is the idea.
Just discovered that running it manually is prevented by Windows 8.1 as you are an unknown author ! I bypassed that and ran it anyway and it’s working with current data being received.
Any advice to overcome the initial block would be welcome -
