Is the Smart Controller able to work with the Mavic Pro Platinum?  Being that I think the MPP is "Occusync."

No, it's not compatible with the MPP.

msinger, thank you for the answer, good to have someone answer a question.  So I guess the smart controller is just compatible with the Mavic 2?

Hello and good day HH1. Thank you for reaching out and for the inquiry. As of the moment the DJI Smart Controller is not compatible with the DJI Mavic Pro Platinum.
