I believe SmartTubeNext (blue "S" app icon) is the successor to what I previously used SmartYouTubeTv (red "S" icon).
Anyways as of this morning the SmartTubeNext isn't playing videos. Everything loads up fine, you can search etc, but when clicking to play a video it just stays black.
Anyone have input?
Did you try to update to version 11.40. This version have a unplayable fix.
