We have had the Power BI Log Analytics for Analysis Services Engine refreshing successfully until last week (July 30).  The error message is:

Hi @Anonymous ，

I wasn't able to reproduce your question.
According to your description, is this problem without doing any additional operations it suddenly appeared?
A few days have passed since you posted, did you retry today to see if it has returned to normal?

After redeploying the template app on (updated 8/2) on 8/4 it works. 

They were a day late with internal changes.

I was able to capture the queries against the Power BI Log analytics workspace.  The queries have WorkspaceID and WorkspaceName,where the logs have PowerBIWorkspaceId and PowerWorkspaceName.   I can't download the report / dataset.  Would anyone know who to contact on this issue?

FYI   The https://aka.ms/BYOLATemplateAppsDocs_AS link for on the Template App support section and in the "Help" page doesn't work.
