How do I receive stereo signal from iPhones in Live Multicam?

Hi. I am using 2 iPhone 14 pros and my iPad Pro to create a live Multicam and as I am recording, my phones are showing up as mono and at times as stereo. My Ipad clip shows up stereo. One of my phones have a rode clip on wireless microphone pair that makes a stereo. How do I receive stereo signal from the phones in Live Multicam? It seems that most of the time the phones show up as mono. Even in Final Cut camera I can see on the phone the stereo signal but when it shows up in the iPad in Final Cut Pro it shows mono. Please help.
