Slack Begins Forcing 2FA for Workspace Admins Without Providing Notice

My experience: I was in the middle of typing a message when I was immediately locked out with a modal. I was really concerned at first that there might be a phishing attempt happening or something like that. Not the typical UX I would expect for an application recommending or even requiring 2FA.

Users report being kicked out of huddles and issues with signing in with 2FA.
