Aig planes dont show up en route!

LIttle late, but how have you noticed that it is resolved in P3D? I’m flying on the latest version, with AIG enabled. Exactly the same issue as descibed by OP, but my traffic enroute has not appeared. I arrive into the airport with 0 traffic and then once I land, I start noticing some aircraft taxiing around a departing. Strange thing is that at the same time as me another AIG aircraft departed from the same airport and did a similar route and I was able to see just this 1 aircraft the entire time. Any ideas?
