YouTube pairing and casting videos to U1

Hi everyone,

I'm quite new with the Minix U1, so I apologize in advance if this question has already been answered (could not find anything by searching):

I don't seem to be able to pair my Android smartphone with "TV YouTube" app, I can't find the pair option in the settings menu in the Minix. Do you know how can I do it?

I have the latest firmware version, not rooted, and I think the latest version of the app too

Thanks!
