Please let me know if you need anything else.
Thank you!

Thanks for reporting. This is somewhat related to #754
YouTube is detecting Playlet as not an official client, and is not returning all streams with all quality levels.
Instead, it is returning a single stream of 360p. (itag=18)
And then, it is refusing to play it (403) because again it doesn't think it is a legit client.
Still investigating
