Spotify cannot figure out that I don't listen to German/French podcasts/books and constantly recommends them to me. My interface is English, I listen to primarily English but also Russian/German/French music and will often specifically click off of French/German music and after 5 years it still cant figure out that I don't want fucking French and German books and podcasts. WTF SW people, I thought this was your bread and butter...don't even get me started on youtube ads which seem to follow the country you're currently in, like...how haven't you figured out which languages I speak after using you for 10 years.
