Once I was looking at this video https://www.youtube.com/watch?v=TTUQ8Idrowg and commented on the top comment
Since then I get notifications about each new reply. I clicked on the three dots on the notification and pressed "Turn off reply updates", but I still get notifications if someone replies to the original top comment.
I also found the option to disable comments in general from other videos.
But I only want to disable notifications for replies on that particular comment. Is that possible?
