Requires outdated t-mobile hub app. I was going to ditch spotify for tidal, but immediately got a notification that a tmobile 'hub' add on was required. Pretty much everyone who has downloaded the t-mobile hub app says it has messed with their phone. I'm not even going to mess with it, if you can't create an app that works without another app then I guess you don't need my money. So, I guess I'll give youtube music a shot instead.
