AiG TC has been working for me since SU10, but the whole simconnect thing is as erratically as before. Smaller airports don't seem to be a problem, but when you start from a larger airport (e.g. LEMD) it's much more likely to glitch. Unfortunately, for some of us that also includes loss of GSX and even 3rd party airport scenery models. There was an auto update for AiG TC a day or two ago, but I can't say I've noticed any difference so far. Worse though, is that if you check the development updates on the AiG forum it seems like they are not too keen to keep releasing major updates for MSFS, and I don't blame them given all the hassle it must be to work around all the bugs and limitations in the sim right now.
I have no idea how the FS Traffic team are going to fare any better given what AiG have said in their various dev blogs, but here's hoping because good GS, Traffic and ATC are pretty much essential cornerstones for those of us interested in airport/airline ops.
