Hello,
Did anybody ever notice when using a remote metric that does not exist on the local system,

Using configure will search on the local system, metric will not be found.

Using above "Configure in data explorer", sends you to the remote system. Tile can not be saved.
The work-around means manualy copying/modifying a Json, you never to be able to save the tile with the unkown remote netric,
Thanks Marc for noticing!
KR Henk
