I would not use YT either without Smart Tube Next on my Shield TV lol.
YT premium can fuck off until they ad Sponsorblock... Which they will never do.
More people need to know about Smart Tube. Like sure my desktop computer is totally on ad lockdown but my tv isn’t connected to my computer so i was stuck with normal youtube on my amazon fire stick for the longest time until i had enough and went looking on my own. Never going back. Should work on most android smart tv devices.
