Refresh Semantic Models Activity - Dynamic Content not saving

Hi JaneLHunt, 

This is fun. 

I think there's a couple of things going on here. 

The first is the system not showing the add dynamic content button, but then allowing you to add dynamic content when you type @. Not everything supports dynamic content, and I have a gut feeling that the @ workaround works visually, but then doesn't actually save it. 

This doesn't explain why the field that does have the dynamic content button also doesn't save it however. 

I feel like a ticket is in order, either you're able to do things in the UI that aren't allowed, or you're doing things that are allowed and they aren't getting saved. 

In the meantime, my approach would be to use a notebook to refresh the model using the fabric APIs. Not ideal at all, but functional while Microsoft Support figures out what is happening with the refresh activity.
