Hi @stefankoch-OLD
I had the same issue from a french perspective 😉
To fix this issue, I had to configure the Language + Region settings on the Azure portal, and set the Regional format to English (Europe) ... it was previously on France.

After a refresh, loading a workspace (or the account console) made english as the default language without having to update at the workspace/account console user preferences.
