There is a delay in connection between Ultra and YT Music. You must wait around 15 seconds after you click send to Wiim until the song starts.
When you pause the song and switch it to next one, sometimes, for 2 second, the old one is still playing, and only later the track is switched.
Some other very little (~2 seconds) delays sometimes appear in different situations.
The last one is maybe (or maybe not) my mistaken imagination. I feel that sometimes the quality of the song is terrible, literally, tragic. I don't know what it is, but sometimes it's like listening to a slightly better radio with bass. As I don't see quality on the Wiim screen, I cannot say more.
