Hi Fernanda, that language mismatch happens because OneDrive web apps maintain an independent regional template that can completely decouple from your global Microsoft account dashboard. To fix this permanently, open OneDrive in your browser, click the Gear icon (Settings) in the top right, and navigate to More Settings followed by Regional settings (Mais configurações -> Configurações regionais). From there, explicitly change the language preference back to English (United Kingdom) and save your changes. If the setting still doesn't stick, the localization string is being kept alive by a stubborn session token; you can force a hard reset by clearing your browser cookies specifically for live.com, microsoftonline.com, and sharepoint.com before logging back in.
