Huge thanks for looking into this! I came here to post about this same issue. Glad to see I’m not the only one experiencing this. It seems to happen every vatsim flight on FS2020. When i land I see no other aircraft. Once I restart my sim and reload vPilot all the aircraft that should be there finally appear. I hope the fix is soon since FS2020 is my only sim and vatsim is too good!!
I agree with this. I fly all the time successfully on MS2020 and VATSIM. I use the A320NX mod which adds a ton of capability and Navigraph in case I have to fly an approach manually cause the FMC does not always work as desired. So far no issues and you can't beat the visuals!
