Looks like @YouTubeIndia is facing Notifications issue from the past few days. Have worked on some good videos & no notifications sent.
Noticed the same on a few other Youtube Channels and everyone's views are down. Any ETA on this issue being fixed? @TeamYouTube
It's because you not subscribed to @pewdiepie once you sub to him, will unlock the notifications feature. I did this now all my subs get my videos.
