It was removed from the MacOS version, yes. I’ve been using Microsoft Word since 2004.
Edit: also think about what you’re saying: they “added” autosave (why didn’t they already have the single most obvious feature in a word processing app?) but they don’t let you autosave unless you put your files only on OneDrive — not locally. Think about how bizarre and shitty that is… and that’s for paying customers.
You just spent pages defending Microsoft for having no autosave feature on a word processor. Maybe time to re-evaluate your life choices.
