The tile could not be found you may be missing a dashboard pack
This message may be seen on a dashboard tile:
The <Tile name> tile could not be found, you may be missing a dashboard pack.
This error can occur if your Dashboard Server edition does not include the tile referenced by the dashboard. This can happen if you have imported a dashboard pack that was created on a Dashboard Server edition different to the edition you are using, for example you have imported a dashboard pack created on the SCOM edition into the Azure edition.
You can either download the dashboard pack intended for your product edition from dashboards.squaredup.com or remove the affected tiles from the dashboard.
