Your suggestion has been absolutely on the point
The event is SCREEN CONTENT: "On Hold" ("In attesa" in Italian, not sure in English) - It only appear on active call
The action is UI INTERACTION: Click [Record]
It simply works
Thank you very much
Sorry to pick up an old thread but I think you are right. The right working sequence should be the one you highlighted: it should START ACTION, ONLY AFTER call is ANSWERED.
I'm new to MacroDroid, I've installed it today for your same reason, to have call recording always on, and have developed...
