@TeamYouTube why are half my notifications coming in days after the videos have been uploaded? I just got notified about @shanedawson publishing a video "7 minutes ago" that i watched YESTERDAY!
Hmm double check your bell settings for the channel and make sure you've opted-in to receive all notifications and not just "occassional". After that, make sure your app and device settings are turned on: https://goo.gl/UCRcbp . Let us know if things still aren't working!
