> If Teams is built as a website, do we expect them to test every feature of every release on every browser? If they've got good unit tests, they may test every feature of every Teams release and I assume they test on all the browsers/versions that represent the vast majority of the market. They don't bother supporting FF Nightly because it's not important to them, not because of some "accident" in the code.
