Yeah, this means we have to take this into account when we set up our rules.
Rules that apply on Windows must also now apply on chromeOS.
No secondary sign-in must mean just that, but I fear we may have to live with some confusion for a while.
Unless Chrome and chromeOS devs have actually talked to each other, and realised that restricting sign-in is really important for Education.
