Do you still see this broken? I just tried it and it seemed to work for me.

It reproduces for me now on all browsers. I guess the app is needed from now on (see attachment)

Tested with:

Browser / Version: Firefox Release 132.0.2 (2016055415-🦎132.0.2-20241110192737🦎)/Firefox Nightly 134.0a1 (2016056767-🦎134.0a1-20241117211558🦎)/Chrome Mobile Version 131.0.6778.39

Not sure if desktop compatibility should be reported on this issue as well, but I tested on Firefox 132.0.1 on Fedora 41, on a brand new profile with Tracking Protection set to standard and no extensions. Previously I would land on the "this browser is not compatible" page, but now, after successfully authenticating and a couple of redirects, I only see a blank page at https://teams.live.com/v2/ . It works just fine on Chromium 130.0.6723.116 (both as a PWA and on the browser), I use it daily for work.

teams.live.com (personal) is different than teams.microsoft.com (corporate, which works). This bug is about teams.microsoft.com (we have others for live). This is known to work on desktop, and apparently they now block mobile use for all browsers, so there no longer is a webcompat issue.

We are tracking teams.live.com (the consumer version of Teams) in bug 1904972. This bug is for the enterprise version.
