My understanding is that if we set datasourceStrategy="preferAppLevel"
when we open a route with Sitecore Experience Editor and we want to add a component the data source location should be in Components folder at app level (appDatasourcesPath="$sitecorePath/Components"
) but for us it takes the route level folder so it seems that updating config from preferRouteLevel to preferAppLevel has no effect.
We are using Sitecore 9.2 and JSS 12.
