Power BI Report Server (Oct 2020) changes "changed by" date before modification

[ChrisMuthmann]

Given a Power BI dashboard on Power BI Report Server with a direct query connection to an analysis service cube. Each invokement of manage in the browser leads to a change in the "changed by" date just before any modification takes place.
This does not happen with import queries.

Can anyone verify this or give a hint how to prevent this?

I can confirm seeing this behavior in the Oct 2020 release.  I had not noticed that it seems isolated to direct query on analysis service cubes, but after checking several affected dashboards, they're all configured this way.  We unfortunately rely on the timestamps to support various workflows, which we've had to disable.

This bug still exists in the Power BI Report Server January 2021
