Problem with Query validation in Dataflows

I began experiencing an issue with dataflows where I am no longer able to save queries, I get the validating message for more than 3 hours and it doesn't crash or advance. Previously it was taking about 3 minutes.



I already tried running a similar query in the desktop app and it runs really fast so I don't think it's the complexity of the query (also it was working fine last week)


Has anyone encountered this issue before?

So the only solution I found was leaving it overnight and it evenutally finishes 😕

We are still having issues with this.  For our Use Case, we just needed to switch the underlying source from Sharepoint Online folder to a Gateway folder entry.  Change was super straight forward, but when we tried to save, the validating queries never returned (think it actually times out after 24 hours).  

The one hack we discovered was to export the JSON, edit the necessary lines and import it back in. Then we just went to the DataFlow settings to bind the Gateway connection.  We tried editing the DataFlow afterwards to see if it still gets stuck in infinite validing queries and surely enough it did.  This is certainly a bug that Microsoft needs to look into...
