During a long flight to Scandinavia, I was confronted with a peculiarity of Skydemon that really annoyed me.
When searching for aerodromes with suitable fuel, I used the "Find a destination" and "Fuel availability" function.
The "Airfield Highlight Type" selection is inconveniently deactivated as soon as you tap anywhere on the map. This often happens unintentionally when moving the map or zooming, for example.
