Some features don't land in Europe because US companies can't handle the amount of languages. For them it is English and maybe Spanish or Chinese because they don't care how heybmake money.

I have not been able to switch language in Sheets since 2018, and I've changed any possible setting (even account language).

All guides are in English and I'm stuck with Sheets in Italian.
