Refreshes for Datasets containing Calculated Tables over Direct Query to AS started failing Mar 30th

Thank you for your service!  Can you please post an authoritative link to more info from Microsoft (bug number or kb number or blog or something)? 

I'd like to open a support ticket as well, and your prior work may save others some effort (getting thru a couple layers of support).  It is an obnoxious bug.  A report developer shouldn't be able to spend several days building something with the PBI desktop, only to find out that their report won't refresh after being published to the service.  That wasted effort is not acceptable, even by Power BI standards.

I suppose the official reply will include some stuff about the fact that this directquery feature is still in "public preview".  But that message is starting to seem like nonsense, considering the degree to which the functionality is promoted by community leaders, and how very long it has been in "public preview" (3 years?)
