First off, gateway installation was a bit strange in that I had to manually start the configurator and it never asked me for the Windows permissions. I did login as a new Office 365 user created specifically to troubleshoot this. The icon does show up in the system tray and does tell me it's "Connected: You're good to go!".
Okay so here's the skinny (have tried countless options and we're now down to this)...
- The dataset was created in Power BI Desktop regular NOT Pro;
- Again, I added a PowerBI user specifically to see if I can get this going, so the user has no baggage;
- User logs in and has nothing (of note the Settings » Manage Gateways shows nothing);
- Uploaded the dataset to the new user, and it shows up;
- Click on Schedule Refresh for the Dataset and I get this...
