Additional meeting and call-related features and issues within Microsoft Teams for Education
I bet Microsoft doesn't use their own tools in this way. Otherwise, they would realize very quickly that their perhaps so great perceived feature causes huge problems. Eat your own dogfood!
Much worse: They provide a support channel where obviously no employee is reading. If I'm wrong, it suggests that Microsoft simply doesn't care if their tools are usable or not. the main thing is that the money rolls in.
