Netflix app suddenly in Spanish, where to change?

I'm in Germany and my Netflix app now shows everything in Spanish, including the film descriptions. I can change the language when I watch the film, but I can no longer read the film and series descriptions. Where can I change that?

Account settings, / your account = Cuenta

select, language = idioma

Then you search for German, German

Thank you. Will be correct, the page could even translate to German in the browser. Strangely, the language setting is missing in both Spanish and German.
