The funny thing is that TOGA was in the original Asobo GNS units, and when WT took them over is when it stopped working! I went through a long back and forth with FSW in their 414 because it had stopped working for me, and eventually they told me the new, mandatory WT GNS units did not support the TOGA Kvar and as they used the avionics AP instead of coding their own, there was nothing they could do about it until WT put it back in.
I was pleasantly surprised to find it working in the Starship, where I have the GNS disabled, as Nick has also traditionally relied on the AP of the underlying avionics (I think). For me, that has meant the WT GNS units, as I am not interested in using the various flavors of giant touchscreens, so for most things I've given up having TOGA work at all.
However, it seems like this latest batch of nonsense has him just doing the whole thing himself, which I imagine will eventually work its way back from Starship to the Dukes, TBM, and Professional series.
