Yep, That did it.
As soon as I added the mod back (Easy Airlines + Aircraft Matching With Default Live Traffic) I popped back into O’Hare and YYZ and live traffic was there with nameplates and lights.
Without the add on, I couldn’t see any live traffic.
Confirmed by nameplate one was a SkyWest flight inbound to O’Hare the other a Westjet flight outbound of YYZ.
Guess it’s still “broken” but if you use that Mod, it seems good!
