Poly Focus 2 headset remote answer hangs up the call instead of answering

Hi scheived,

Have you enabled Sync buttons on headset in your audio settings?

zoom support article states:

"The Zoom desktop client for macOS and Windows, as well as the Zoom PWA, supports the following USB devices. If your audio device is on this list, enable the Sync buttons on headset setting in your audio settings. Otherwise, disable the setting."

Your poly focus 2 is on the list.

Yes, the sync option in settings, Audio is on by default I have not turned it off. Previously for troubleshooting I have tried turning it off as well as off then back on again with no change. 

I'm still trying to figure it out but through some testing it seems this is an issue with the poly lens software not working with certain hardware revisions of the Poly BT700 USB dongle. It will work with some but not others using the latest firmware release. 

What I found through a lot of testing is that the latest version of poly lens is not working with Zoom. You need to go back to poly lens version 1.2.5875 then in lens press the gear options, softphone, give it a second to load and make sure zoom is being detected as target softphone. This got it working for me.

There is also a difference on which usb dongle you are using, the old one or the newer low profile one, the older one seems to work in more versions of lens. I also tried diff firmware versions but non seemed to make a difference with the remote answer/hangup issue.

How can I go back to poly lens version 1.2.5875?

Poly has released Lens version 1.3.2, I've tried this version and no change, remote answer still not working. Nothing much in the release notes.
