Hi,
I can see other aircraft when I’m airborne. Some days ago I was in a holding close to EIDW and numerous other aircraft around me were visible (at least the lights, because it was nighttime) and also in my moving map I can observe other Vatsim traffic within 40NM and +/- 5000 feet ( for charts and moving map I use the Electronic Flight Bag from aivlasoft.com, I don’t know if other moving map software does this too)
So finally I have no idea why this is working in my setup and not in others
