Cant pop out meetings from teams chat

Hi everyone,

I am having this exact same issue.  The pop-out option WAS working on both of my devices at one point about a month ago, but then one of the devices (the one I normally use for video conferencing) stopped letting me do it.  It is greyed-out, and if I hover over it I get the message "This isn't available on your device."  I have tried everything suggested here (and then some) all to no avail.

Interestingly, on my other device I still have this option, but that is not the device I use for video conferencing because of how my workspace is setup.  The working device's Teams also shows a slightly OLDER version number (1.5.00.28361) compared to the device where it isn't working (1.5.00.28567)

Another possibility I considered is that the device where it does work is running Windows Enterprise and is managed by the organization, while the device where it doesn't is running Windows Home and is a personal device.  (NOTE: Both Teams instances are signed into the same AD account, although the personal device's Windows login is a local account).  I'm confused as to why this should matter though.  If anything I'd think the organization-managed device would have more restrictions for experimental/public-preview features.  Is it possible this feature is only available on systems running Enterprise with Office 365 subscription, etc???
