cayo perico replay question

(sorry for my bad english this is not my first language) so i have problem with cayo recently cus im playing on a series s with the xbox one version because my friend only has an xbox one and when we get the final cutscene mine is way ahead from his so i don’t know when to leave, we tried every way to leave(and the best part is that we get 0$ and the heist get lost). Can someone have some tip or something to to this to work?
