My Scenery is not showing even though it shows as installed in Content Manager

We sometimes see an issue with the MSFS cache not clearing itself after installing third party scenery. A good way to manual refresh the sim is by clearing your scenery indexes - 
 

To do that locate your folder by following the path below.

(MS Store) \AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache\SceneryIndexes

(Steam) \AppData\Roaming\Microsoft Flight Simulator\SceneryIndexes

Then delete the contents inside but leave the folder intact. (The indexs will rebuild on next load of FS)

This should solve the issue.
