I am having a similar problem myself using 'Logitech ClearChat Comfort/USB Headset H390' on my Android phone B131DL, which is using Android version 11....
I have connected my phone and laptop using the Windows Phone Link app., but when I get a call on the phone, I cannot find a way to transfer it to my laptop through the headset?? Actually, I can send the call to my headset, but they are unable to hear me talk through the microphone for some reason.
I am using Windows 11 on my laptop, but think I may need a different app. to answer calls using my laptop and would appreciate helpful instructions Please.
Thanks in advance!!
I would like to add to this that I have Android 11 running on my phone, and though there is a workaround of sorts to this problem, apparently it will not work on my specific version of Android, YAY what a shock!!
