iPhone calls using Bluetooth people can’t hear you

I just purchased a new iPhone 14 from Apple, from a 6plus that I had for years. Now when using Bluetooth headphones, car Bluetooth, etc., people can not hear me, I have updated the phone, checked for updates on my other devices, and found other I phone users with a newer phone have the same issues. I have powered off, speakers work fine. It’s ridiculous to have to drive and disconnect my car Bluetooth to switch to to speaker just for callers to hear me. I have been team Apple for years but if this is not solved, I may have to jump ship….. any fixes for this? 6plus had no issues with Bluetooth or people hearing me-Fyi
