When I search on Podcasts on iPad Pro, found podcasts are in German not English

I bought the iPad in German and I made my country Germany back then. Now when I search on Podcasts, all podcasts shown are in German language. How to fix that? I want to see Podcasts that are in English too. I have iPadOS 15.0.2 betta. I bought my iPad in Austria. At first I put my language German, and my country Austria. But now I have changed my default language to English, and my country to United States. I also changed the preferred language in podcast settings.
