This is a tangential aside, but the school system our kids are in get "Your credentials have been leaked and should be changed immediately" warning from iOS devices when logging into their Microsoft 365 accounts. Seems like a commonality between the two that happened recently (2 weeks ago for us). This is just an observation, nothing more. I'm sure MSFT spends a fortune on securing that platform (among other things).
