Nice to see some progress made here. The native Linux app has not seen any meaningful updates since the preview was released back in 2019. The web version has been substantially more feature complete for quite a long time now and is what I've been using in preference to the native app. I'm not seeing a huge amount of difference between the web version and opening it as a PWA yet. It opens as a separate window, but you could already achieve that in chrome by using the "More Tools -> Create Shortcut..." option.
The PWA offers access to more capabilities, including custom backgrounds, gallery view, reactions,
Using a custom background is something that has worked in the web version for while - I can currently open teams in a browser tab and do have the option to enable a custom or blurred background. After installing as a PWA however I'm not seeing any options to enable this (toggle is missing when starting a meeting). This seems like a feature where the PWA is less functional than just opening the web version directly?
Can we have multiple Teams windows open in the PWA?
I can right click on the launcher and select "New Window" which works as expected.
