I have the Power BI Log Analytics template app installed but it doesn't refresh as of June 26st. I reinstalled the app already a couple of times to make sure that I have the latest version.
I've noticed that around the same time my other reports based on log analytics that I created myself started to fail because one of the dimensions was changed (WorkspaceID --> PowerBIWorkspaceID). Could this be the reason?
As far as I know, the schema of Log Analytics includes WorkspaceId property which uniques identifier of the workspace containing the artifact being operated on, not the PowerBIWorkspaceID dimension, so it could be the reason of this issue that you can check it.
