Most of my current company runs on Teams, which is such a massive self-inflicted gunshot wound. It must cost billions in lost productivity across the globe, just dealing with how terrible it is.

A few examples that happen pretty much every day:

1) The teams interface takes upwards of 60 seconds to load, from the moment I've gone through the auth process and the Teams logo pops up, from when the UI actually renders the sidebars and the first chat window.

2) It frequently fails to load new messages after resuming an existing session for a few minutes. It shows everything up to date, you can navigate between chats, but no new messages or unread message counts update. Then after s a few minutes, it suddenly works, but it's impossible to tell if it's working and you don't actually have any messages or if it's in this limbo state.

3) When you need to reauth, the app seems to work, again showing all the previous messages, but there's this tiny toast at the top saying that you need to log out.

4) The log out button doesn't actually work. On Chrome, I've had to use devtools to clear my cookies & sessions for it to get into a valid state where it would actually let me sign in again. The Mac app just goes unresponsive and needs to be forced to quit.

I didn't feel the tiniest bit bad for all the companies going down thanks to MS this week. Alarms have been blaring for years and nobody cares.
