The song should be playing 10secs or more to reproduce this bug!

1. Go to home
2. Click on "previous track/back"
3. Video will stop/pause and "back button" does not work.

Pressing "back/back button/previous/track" should repeat the song.

Platform (please complete the following information):

Additional: is there also an option for volume normalization in the app? Some youtube videos are louder.
