Calling Issues

I randomly have trouble with my series 7 Apple Watch where a caller can’t hear what I’m saying. I can hear them, but they can’t hear me. It happens at random. I restarted the watch and also reset the watch and repaired my 12 pro max to the watch. It still happens randomly whether it’s connected to my phone or using the cellular connection.

I called my brother and it happened again while connected to my phone. Transferred the call to the phone and back to the watch, and he could hear me this time. I’m running the latest update on both the phone and watch. Any ideas what I can do to fix it for good or is it just a software bug?
