What does not
When entering a meeting, this error can be reported: "Unhandled exception: page fault on read access to 0x00000000 in 32-bit code (0x003dba47).". Just ignore that error, leave it open. If you close it, the meeting will close also.
What was not tested
Looks like antialiasing isn't working out of the box at least.
Generally it seems usable, but not quite stable. For normal use, where none of the features are required that only the App offers, I'd certainly still use it in the browser.
Compared to other Wine 5.x versions tested, it is already a large improvement though.
