Hi. I've had Spotify (premium) for years and suddenly my data usage has gone through the roof. I haven't changed anything and have the playlists I listen to all the time offline and am actually using it less if anything. My data usage has almost tripled in the last month and I've narrowed it down to Spotify. It's cost me an extra $50 in data this month. I've read about Spotify having a bug that causes it to use cellular data even when on WiFi. I'm assuming the app has had an update that is causing this problem. Has anyone else experienced this and can I get hold of anyone at Spotify to sort it out!
