Same for Linux and office365
Word 365 on Linux is literally sabotaging you, at random deleting texts you previously wrote. Whole sets of words just randomly disappear as if you never typed them. You type them, they're there, you continue typing and 1-2 paragraphs later, part of the text you wrote is suddenly gone. No undo available or anything, it's as if it never happened.
It got to the point heere i wrote documents in Google drive, then exported then and imported them in word 365, that did work
Then I found out that all I had to do is send M$ servers a user agent header saying it's Windows 11 And suddenly everything works
