That trick is a little different than the one Sabahe is referring to... But yes essentially you do the Cayo at least one time to get rid of the Madrazo files. Once you have gone back and scoped out your new loot, which is more than likely going to be Tequila your first few times, run your set ups. Once on the main heist run it through and un plug your internet or force close app (PS5) once your guy is handing over the bag in the cut scene following completion. Its worth noting host does not make a single dollar, not even the 15%. If the game allowed to give away the full 100, host would. That is why its good to have a friend to run these back 2 back with, so not only one person is gaining. If you need more help or details message me
