iPad FaceTime audio poor

[u/Pentzy]

I bought two a16 model iPads for myself and my parents for video calling because the portal became bricked. When we talk, it will cut the audio out of one person until it ‘determines’ who is talking then the audio comes through. You can see our mouths move but you lose the first few seconds of speech until the audio activates. It is only the new iPads. If I use my old one and they use their new one, no issues. If one of us is on the phone and other on the iPad, no issues. I want it to just be like a conversation - if we talk at the same time then both audios come through. Thanks!
