In the iOS Settings, under Mobile Data, I blocked Spotify from using mobile data. Although, as soon as i'm off my Wifi, spotify starts to use mobile data, which i can easily prove in the mobile data statistics. It seems to be a pretty old or recurring issue. What is going on there? I can find reports back from 2016 talking about this kind of issue. Spotify keeps sucking my prepaid budget... and I'm in a paid spotify plan...
