How do I go into Blitz Play?

After I've gotten the masks, trash truck and tow truck, I hide the getaway car and can't progress to the actual heist. I've been stuck here for about 5 months. Do I need to play the other side mission in order for the heist to show up? I'm really confused on what needs to happen next. I played for hours and still no blitz play.

Solution 1:

There are a few prerequisites to starting this mission. Each character has side missions that must be completed before the actual heist can be played.

• Franklin will receive a call from Lester. Go to Lester to start the mission:

• The Hotel Assassination

• Trevor will need to go to Floyd's apartment to start the mission:

• Scouting the Port

• Either Franklin or Trevor can head to Franklin's home to start the mission:

• Hood Safari

• As Michael, head to his home to start the mission:

• Did Somebody Say Yoga?
