I am working on a project where I$$m implementing a map from Mapbox, and I$$m trying to implement a SymbolLayer in my Style. The data for the SymbolLayer is based on a GeoJSON file from a public source, and it contains data about harbors $($n$$dhavner$).$

To keep things simple, I$$ve made a small test$-$program, which you can see in the screenshot.

I don$$t get any errors in my logcat$,$ so I$$m assuming there isn$$t anything wrong with accessing the file $($which is in my assets$-$folder$).$ I also know that the layer has been added to my stile, because I$$ve added a logcat message which prints the names of all the layers in the Style, and it printed this: $$Layer ID: nodhavner$-$layer$$

However, the problem is that I don$$t see any symbols on the map. When I run the app, the map is displayed, but not icons showing harbours.

I have the necessary permissions $($internet$/$network etc.$),$ all the necessary imports etc. I don$$t get any issues$/$errors$.$ The icon $$triangle$$ is in my Style, which I downloaded from Mapbox $($Maki icons$).$

What could be the reason for the icons not showing on the map, and how can I fix this?
