"Listen in background" seems to be bugged. Great app otherwise. – Tubex - Videos and Music for YouTube Review

This app has been great for the year or so I've been using it. However, the "listen in background" feature has had problems for the last few weeks. At first I thought it was outright broken - I'd hit the headphone icon and switch apps or lock the phone, and the video would stop. However, I've learned from reviews on this page that the user can hit play on the lock screen, and the video will resume. While this is better than nothing at all, it's still a small annoyance that wasn't present before. I hope it gets patched soon.
