I've noticed that I'm not seeing any online (VATSIM) traffic on the PFD/MFD displays.
I've gone through the options on both the ATC/TCAS control on the FMS and on the PFD/MDS options.
Also, if the TCAS control on XP is set to LiveTraffic, it doesn't show also.
I might be missing something (most likely) but, just as a reference, on the ToLiss aircraft, TCAS needs to be set to On instead of Auto (why, I do not know).
Traffic (Online or Live) works on all other aircraft. So, I'm guessing I'm just missing on an option somewhere.
Screenshots for reference.
And thank you for this outstanding piece of software.
