Teams does too much but slack is just a chat app? That’s just not even close to true. Slack does way more than teams. Which is why I wish my company would drop teams so I don’t have two messaging apps to worry about.

I do have to say I almost never have an issue with teams calls. I’m pretty sure most IT departments just do a shit job of configuring it because if it was the app, it would happen to everyone. 99% of my teams calls work without any issues, including big meetings with dozens of people.
