Prior to updating to firmware 0.2.3, I was able to use my EarFun Free Pro 3 earbuds as a headset in Windows 10. After firmware 0.2.3 was installed, I could no longer use the earbuds as a headset. I had to change to headphone which doesn't allow me to use the built in microphone on zoom calls.
I have tried uninstalling the earbuds and installing them again, but that doesn't resolve the issue.
