To that end, I'm not sure what benefits or cons using the "-nocookie" variant of the YouTube services have. I was (at the time of this topic posts creation date) "Today Years Old" that I realized it was even a thing.

I did some very light studying on nocookie domains, and from the little research I did, it can have a possibility to save on bandwidth. So edit this file with care in terms of its final domain output, adding the &autoplay=1 should still work with the -nocookie domain.

Since the UNA devs decided to force this -nocookie domain in their code, they might have a better insight into why they decided upon it. @LeonidS @Alex T⚜️ @Anton L any insight?
