Problem with setting "Users can work with Power BI semantic models in Excel using a live connection"

Hi Anonymous 

That's what I meant yes! 
I'm on this version (desktop):

Not sure how to get PBI service one.


Today the problem solved itself just by reconnecting the report to it's semantic model again, It didn't work yesterday.

But I am still unable to upload it to service:

I don't know why because it doens't give me any context at all...


Just so you know, we are working with GIT (preview pbip Powerbi Projects). If I save it as .pbix then I can upload it. Maybe it has something to do about being in preview but it didn't happen before and I don't know how to report the issue if needed.

Thank you!
