I need help guys... I have tried to find my own answers, but it seems I don’t quite know enough yet to help myself out of this issue. So I have a lumanier QAV-R 2 and it connects to beta flight and pairs with my DJI smart remote just fine. I can see my throttle working in real time as I move my joysticks. I just got a geprc thinking p16 which seems to also pair with my DJI system just fine but doesn’t seem to react to any of the controls. My issue is I can’t seem to configure the flight controller properly to get beta flight to recognize that the flight controller and the smart remote are talking to each other. From here I can’t set my arm switch and beeper etc. I just wanna fly the damn thing and I’ve been trying to figure this out for a few days. What am I missing?

Pairing GEPRC Thinking p16 with DJI FPV System. All items registered fine have updated firmware. Able to fly my other drone just fine.
