Hello Tim,
sorry, I'm using the latest version of SkyDemon Plan (3.12.7.0) and there's no FIS frequency shown in the Virtual Radar, neither highlighting an airfield nor an airspace. Only thing I see are the FIR boundaries on the map.
Could you please confirm, or even better re-apply this feature in the next upgrade?
Btw. on Android everything works fine.
Thanks, Niels
