Recall that initially this mode became available on iOS in April. Now it is available to everyone on PC. More precisely, to all paid YouTube Premium subscribers – it is they who can find a new item in the quality settings and activate it. Actually, this item is also available for those who do not have a subscription, but it will not work to activate it.
