Nice to see an improved PWA experience for Linux users
But it's not. It's the same PWA experience that's already been available in Chrome for a while now as far as I can tell. I even uninstalled and re-installed the PWA, because I couldn't believe that it's improved absolutely zero since I last tried it a month or so back. Where are all the new features MS mentioned as a reason to go full PWA, background settings et al.? At this point, it seems like It's exactly the same as running the web client.
And, as others have pointed out, a major step back from the Electron app. There's no longer any way to set it to the specific cameras and microphones I used for Teams, turn on echo cancellation, make a test call... There's not even a tray icon to facilitate quick changes to status! The Linux Electron client was lagging behind the Windows client, but at least it had these basic features.
This really feels like MS just dropped support for the Linux client after using it to get Teams accepted into many companies as a crossplatform solution these past few years.
