so when i am going to skip the set up by joining a new session, i am taken out of my invite only lobby and being put into a public lobby so i am "in the clouds" for a while loading into the new lobby. Is there a method that i am missing to join a new session so fast or is it j RNG. like is there a way to join an invite only session from an invite only session

You have to complete a job after joining the original invite only session and then go back to freemode and it should be set up from there. It's also what allows og heist speedrunners to find a new session so quickly

so if i do a quick mission like blow up before i should be good?

Yea you should be good then to find a new session

thank u !!
