Problems with bluetooth audio

[ccwtech]

I have a T46S FW 66.86.0.5. The bluetooth headsets I have tried have had periodic issues where sometimes I can't hear the caller and sometimes I can hear them but they can't hear me.

I tried these ( https://smile.amazon.com/gp/product/B083...UTF8&psc=1 )and they worked great for a while and then stopped working. I exchanged them for a brand new pair and same issues.

I tried these: https://smile.amazon.com/gp/product/B088...UTF8&psc=1 and had the same issue.

This is the USB adapter I'm using: https://smile.amazon.com/gp/product/B07R...UTF8&psc=1

I'm not sure what broke. I had used the first set for months w/o issue. I don't recall when (or why) I upgraded to the latest firmware so I'm not sure if that is when it started or not. Any issues with this Firmware?
