I purchased the Switzerland mesh through the MSFS 2020 Marketplace and it would not allow me to originate flights from Switzerland or enter across any of the borders. Thank you so much for giving me a code to allow getting it through your site. It now works like a charm. I see a very great improvement in areas I have flown often.
It might be a good idea to either remove it from the Marketplace or have them modify it to work with the flight sim.
