To replay a Heist, call Lester using your in-game phone and select the “Request a Heist” option.
There is also a slight delay between the time you finish your first Heist and Lester’s call for the second Heist. Once you complete your first Setup Mission, there will be a short wait before Lester calls you for the next part of the Heist.
If you meet the required criteria, Lester will give you a call to set up your first Heist. Then, select “Play Heist” to jump into the action. To join a Heist as a crew member without an invite, go to the Quick Job menu on the phone.
