[For the Devs] Why cant i see other players?

[KLIPPENBERG]

Im playing Live, but after 20+ hours i am yet to see another plane around me or on the map. Ive been to LAX, Gatwick, Oslo, Orlando and more, but never seen someone else or heard them on ATC, which seems highly unlikely. Is this due to the server issues? Im playing on Europe West. Please help. I do not believe there are simply just noone on these airports ive been to.
