Sharepoint System Language

[AmoHN745]

Since yesterday the language in Sharepoint 2016 has changed from German to English! Neither I as administrator nor other users have changed anything here, it happened by itself!

The settings in Microsoft Admin Center are still set to German, as is language in all site settings: in German, but the menus of all sharepoint sites are still in English.

Dates have also changed to English format. what could have caused this problem and how can everything be switched back to german again?

By the way, the problem only affects Sharepoint, menus in Powerapps and PowerAutomate are still displayed in German

I can confirm the problem (also german customer). The change of the dateformat is the biggest problem, because we can't add list entries anymore (Error: Enter a date like this: 23.02.2012)

We have exactly the same Problem.

After switching the site language to English the users were at least able to input data.

Best Regards,

Sven

Can confirm the problem for our (german) tenant. This has some consequences for data processing when it comes to dates and numbers.
