Personalized recommendations based on listen history
I recommend adding "You might like" section in discovery tab, which offers frequently refreshed and high quality list of podcasts that are both tailored to my personal preferences and to my location. The problem with the "Suggestions" section in the app is that it didn't change the recommendations based on my listen history, I am not sure but I think it recommends podcasts based on subscribtions not listen history, I wish It considers region, listen history, and likes/dislikes as well.
You can press on the main screen + button to add new podcats, then on the line of orange buttons you can select sugegstions. It might take a long time to refresh depending on how many podcasts you listen to but it should provide a customized list of podcasts you might enjoy
