Chromebooks are basically just laptops that ship with Google’s Chrome OS rather than another operating system. But since Chrome OS was designed to put the web browser front and center, some folks have insisted that it’s not a real operating system – after all, it loses much of its functionality if you lose your internet connection.
Microsoft told About chromebooks that the deadline is the 18th September 2021, but Microsoft did not clarify if the Android apps will stop working or not, though it seems likely.
While the Office PWAs are pretty good, they do not work offline, unlike the Android apps, and it remains to be seen if Microsoft will close this gap.
