About AirTriggers, I've heard people saying (and have experienced myself) that they are working inconsistently, and I don't know if this can be solved by software update. So far, newer levels of pressure have been introduced but consistency is still bad. Another problem is that the right AirTrigger can be accidentally triggered by slightly bending the corner of the phone. At times, it can even be triggered when I'm holding the phone with one hand, which is crazy.
And now on the Macro, it is bugged in background mode. It is technically still running, but the timeline or mapping or something else is bugged, resulting in unintended outcomes. The Macro would run perfectly when in the foreground, but in background every run fails to produce the desired outcome.
