I’ve found a new reason to use the subscribed page - it shows more videos per screen than the home screen, now that YouTube on Android TV has massively increased the preview panel to an absurd degree. There’s barely any room for identifiers, just two or three video previews taking up the entire screen, like I’ve blown up a phone app on my TV. Wtf YouTube?
Swapped to SmartTubeNext. Has all the expected features plus better browsing and an ‘auto-skip sponsors’ mode.
