Just updated DJI GO 4 and noticed that in the release notes it said that you could now control the mavic with a primary and secondary remote. Can't find any more info about this or how to go about doing so. Any info appreciated.

You need to buy another controller. It is only used to train another person. Main controller can take control over the slave. Similar to driving lesson or pilot lessons.

it's also good for someone else to control the camera, no?

Noooope. It is NOT like the Inspire. Just one remote at a time and the master has override over the slave.
Again just for teaching / training purposes
