TMS FNC Maps on Android

Possibly a stupid question ... I want to run an app with FNC Maps on an Android device. I am able to run a simple form with TTFNCOpenLayers or TTFNCLeaflet on Windows. When I try to run it on two different Android devices running Android 13, the app launches but only shows the app icon and not the map. Are there some prerequisites that I may not have considered?

Found the problem .. I have forgotten to add FNCWEBCHROMECLIENT.JAR.

Great!
