In latest release of the User  Manual (v1.6) it appears DJI has removed any reference and description  of functionality for dual controller mode (used to be all of page 47 in  v1.4 and prior) and no more "coming soon" notation either   -.-

I will send you a notification with regards to the reply for our DJI R&D Team. Thank you for your patience and support.

Well that’s a bummer because I just spent the money for a second controller for that exact reason. I guess coming soon sometimes mean not coming at all.

Please advise what you hear back. We specifically went ahead with purchase of several M2 series aircraft based on the dual controller functionality (like the mavic pro series has)  based on the "coming soon" notation and full page devoted to  the subject in the 1st two versions of the owners manual. This is a corporate guideline we have (dual controller functionality).

welcome to DJI.

Stephen -- any word on whether the engineers have this on their R&D plan? Many would like to have the same "two" controller capability that the original Mavic series has. A big step back for instruction and other uses.

Stephen -- did you hear anything back from the R&D team? A lot of requests out there to make the second controller an option similar to the functionality/feature in the original Mavic series.

Bumping this, would also be interested

Agree.

Much needed for a product with  'pro' suffix.

No response from Stephen... can any DJI moderator give an update or at least pass the high interest from users on multiple Mavic2 forums for adding this feature -- as originally promised in the first sevreal versions of ops manuals - to the M2 series?
