Actually today something happened: got a call by the gate as intended, the phone executed the macro, but at a certain point asked for the fingerprint, and didn't complete all steps.
I didn't see it all but I guess that since speakerphone onwards the macro stopped, so I had to enter the digits myself - not a big deal, this is why I set the macro to disable silent and play an audio to catch my attention.
Other than trying to understand what went wrong,
@Endercraft, I was wondering: is there a "screen record" function or any other way of debugging the macro other that testing the trigger (which obviously is done in the condition of an unlocked phone)?
