Enabling Pilot Assist and Adaptive Cruise Control

Can anyone tell me what settings I need to change to have a 2024 Polestar 2 continue moving in traffic jams instead of stopping after 3-5 seconds?

By design, the ACC / PA deactivates after being stand still for more than about 5 seconds. If the car is stopped less than that, it resumes automatically. 
To resume ACC/ PA after stopping more than 5 seconds, you will need to gently press on the gas pedal or use the resume button on the steering wheel. There is no configuration to disable or extend that 5 second duration.   

Since you mentioned   2024 Polestar 2, you should have creeping mode.

Ah! I didn't realize there was a resume button on the steering wheel. Thank you!
