If I pick up my old iPhone 12 Pro Max or iPhone 13 Pro Max it works as intended. Doesn't matter if I'm running iOS 16.1.x, 16.2.x or 16.3 BETA. It always works when using the exact same Apple AirPods Max, Apple AirPods Pro 2 or Apple AirPods 3 with microphone mode "Voice Isolation" activated on a Microsoft Teams call or meeting when using one of my older phones. The issue is only present when using my iPhone 14 Pro Max, regardless of what version of iOS 16 I'm running. With older phones it works regardless of what version of iOS 16 I'm running.
