If you want to save a route entered with the Imgamepanel in MSFS or export it as text, neither works.
Even if you enter the randomly memorized “fs2020” under “Filter export”, no export is possible.
The text export also does not work to enter the route manually in Simbrief.
So you have to use the desktop version to be able to perform the export.
Why is this the case? It interrupts the immersion.
