The request for 1:1 calling Chrome support is still “on the backlog”.
1:1 calling works in Edge.
Group calling and meetings works for Edge & Chrome.
I hope to have more information to share soon.

A week ago I was able to make an audiocall with the HTML version of MS Teams, now that isn't supported anymore. We decided that MS Teams were suitable for us because of browser audiocall support, and now they dropped it. MS: THAT BETRAYING YOUR USERS
We know so many of our customers use Linux and we want Teams to be available for everyone. Stay tuned for more information soon.
