I haven't had any notifications for any of the channels I am subbed to, when I have clicked on the notifications bell. Why is that? I have several channels I know I have clicked on the Notification bell, but I do not get alerted of new uploads. Why is that?
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!
