What happened?! – Muzik- Music Finder & Streamer Review

When I had my iPhone 6s a month ago this was my favorite app to have music on but now since I got an iPhone 11 I downloaded the app again but it only worked for 30 min then I had to delete and download the app all over again and I keep having to do that it is nothing like how it was a month ago, whats wrong with it? This was just the best music app ever and I was really looking forward to having it again but now it won’t even play music tell me it fixable please
