If SharePoint is displaying in a language that is different from your other Office 365 apps, do the following to resolve it:
- Go to https://www.office.com/?auth=2
- Click the circular icon (top right corner) > My Office profile > Update profile.
- Select How can I change language and regional settings?. Open the link in Click here.
- Beside Details, select the ellipses (...) > Language and Region.
- In the Pick a new language dropdown, select English > Add.
- If an undesired language is listed under My Display Languages, hover over it and select the X to remove it.
- Scroll down and select Save all and close > OK.
The change may take a few minutes to process.
