I have an issue that I am hoping someone may be able to assist with. I am using EFB on a networked system. I fly online with both Vasim and IVAO and use EFB as a moving map with the online traffic. Here's the issue, if I am flying on Vatsim say in Europe I can see the traffic all over Europe but when I fly using IVAO and I view the map, the traffic apart from the planes departing and arriving at the airport I am parked at, appear for a few seconds and then disappear. Also EFB doesn't seem to pick up the Center only the delivery, ground, tower, departure and approach frequecies . It doesn't happen on Vatsim only IVAO. I cannot for the life of me work this out.
Any advice would be appreciated
