So I recently got MSFS 2020 and quickly got the 77W addon to go along, however when i tried it with the latest version i noticed there were no cockpit lights at all. I tried all the lights, such as the dome light etc... i have watched some other videos of people where they did have lights. Maybe this is a common issue or just me. Either way any support would be appreciated!

Also how do i use the LNAV? because when i have a flight plan and i select LNAV nothing happens also nothing happens when i change the heading...
