3-way Red Series mmWave Presence Dimmer with Red Series Dimmer

I’m hoping someone can help me figure out how to configure my Red Series mmWave Presence Dimmer to work with my Red Series Dimmer Switch. Thus far I have successfully been able to get both to turn my lights on and off. However, I have not been able to get my presence sensor to also turn on my lights.

My wiring is as illustrated below

I then followed these instructions to associate the switches. In the instructions, my Red Series mmWave Presence Dimmer is “Switch A” and my Red Series Dimmer Switch is “Switch B”.

Any help here would be greatly appreciated!
