Dashboards are not refreshing

It's important to understand what's going on in a dashboard tile. A dashboard tile is not a reference to a report visual, but a reference to a report visual ***AND*** to that visual's filter context at the time of pinning. This is by design and very useful. I will often create dashboards by creating a report, then applying filters to that report (e.g. to a CurrentYearFlag = true, or to a specific dimension category only), and then pin the same visual to the dashboard under multiple filter contexts.

The fact that a dashboard tile does not inherit new filters placed on the parent after the time of pinning is, to my mind, a very valuable and powerful feature (else I'd have to create the same report a half dozen times to support the filters in a single dashboard - talk about unwieldy).

Then there is an issue seen by some users where the data shown in a dashboard tile is not updated as data is refreshed, thus data that now exists in the underlying dataset (and should be visible in that tile's filter context) is not being reflected in the tile visual, whereas it is being displayed in the report visual (when that visual has the same filter context as the tile).

Only the second item described is a bug. The first is a feature that sometimes trips up first-time users.
