Bluetooth earbuds mic stops working after a few minutes

Hi all,

Recently my Galaxy Buds+ Plus mic has had issues on my Mac OS Monterey laptop. The sound works perfectly, but when I join zoom or google meet calls, the mic will work for the first few minutes then stop working. The sound still works fine, though. I've checked and the input mic is set correctly in the settings. It's been ongoing for weeks, and in some rare cases, the mic will work for an entire 30 minute call.

I also use these earbuds with my Android (Pixel 3) and the mic works fine on calls. So I think the issue is likely with Mac.

I've tried resetting my earbuds through the wearables android app, updating the firmware, disconnecting and forgetting the buds from my mac and repairing, turning bluetooth on and off on my laptop, and restarting my laptop. 

I even tried using my older generation Galaxy Buds, but the same thing happens. I don't own any wired headphones to test or use as a backup.

Maybe this is related to the recent Mac OS Monterey update? It was around that time that the problem started, but I'm not sure exactly. 

I'd love some help, thank you!
