@KEEMSTAR @pewdiepie @TeamYouTube @YouTube Let me just point something out, and i really hope someone sees this. I've been subscribed to Pewdiepie with notifications on for 6 months now, and never got a single notification on when he posted.
Let's try turning off recommended notifications by tapping the menu button > Settings > Notifications and uncheck “Recommended notifications”. Also, try switching accounts to check if that makes any difference. Keep us posted.
