The insidious thing about this mistake is:
If you start with one of the Arrows from JustFlight the first time, the "TDS GTNXi" is not yet active and the ATC works normally after you have activated the TDS.
On the second flight, however, the "TDS GTNXi" is already activated and the ATC does not work! Only when you click once through the round on the tablet does the ATC work again.
I use the TDS GTNXi also with the Caronado 337, but there I have to activate the "750" every time anyway, so there is no problem.
