Latest update has a bug (Galaxy S3)
Playlist reordering is messed up. It always grabs the one above where I click. It is impossible to drag the last item in the playlist. Seems like an off by one error.
Please open a ticket using the ‘Contact support’ button in case of a bug.
Try clearing the playlist using its menu button, then repopulate it using its ‘Enqueue downloaded episodes’ menu. Are you still having an issue ?
