I wonder how many of these complaints are due to Teams itself or if it's due to the crappy "corporate" builds deployed to the PCs? My guess is that it's more due to the crappy corporate builds since I've seen so many of them that don't have up-to-date drivers (or have missing drivers), and many of them have multiple competing security scanning software, along with over-strict policies and restrictions that affect Teams.
It’s not great on my Intel Mac. Code formatting via backticks is only applied if I type the last backtick slowly. If I type normally, it just interprets it as non-markup.
