Spotify. Please purge all community "fixes" over a year old where it refernces functinality. We get a new verson every week and the change log isn't. I'm sick of trying to Google a fix, only to be brought here with a post from 2012 suggesting I reinstall.
OK. How >I< fixed the "you are offline" deal is, just close out the program. See attached screenshot. Other than that, a quick reboot will probably bring you back. I think this occurs because the app gets confused if you use in a lot and hand-off between many different connections. That's what I do, car, work, home. And sometimes it just hangs and you have to close it down. If you close it down, it's only a couple of seconds to fix. A reboot is an easy minute depending on the speed of your device.
