Probably want to contact YouTube about that. All Sonos does is pass the information back to YouTube to track, it’s up to them to recognized the data, and act on it. Sonos doesn’t have any control in this case. 

It doesn’t matter where you’re controlling the Sonos system from (PC or phone), they’re just remote controls to where the real work is done, on the Sonos speakers themselves. You’d actually have a real problem if one showed something different than the other. 

Your English is perfect. If you’d put your location in your profile, I’d have used Google Translate to try to make my response easier to read.
