Notifications are only pushed to you when something you are engaged in is being updated. This can be when:
- Someone replied to you in a video which you left a comment
- A request by someone for your reaction
- A user you subscribed to has posted a new video
- A user subscribed to you
- A user liked or commented on your video
So, if you think you’re getting too many notifications you can control your activity at your own discretion. Alternatively, you may turn off your notifications in your phone settings.
