Watch later (not working/playing in build #7771)

Hi,

I just installed build #7771, and checked different actions. I have 3 YouTube videos in my "Watch later", when I press Play - the app pauses for a shot period, and return to the details page. Sometime it goes to the next "Watch later" item, which isn't playable either ...

If I try the same in the latest official app (4.3), it works ...

EDIT: PMS & iOS logs attached ...
