All my YouTube subscriptions have stopped notifications.
Since about Thursday 7/23/20 I have not received a single notification for my YouTube subscriptions to FX Home, @FilmSensei, @HitFilmUniversity, and about 10 others. This is very strange. I have gone to each YouTube channel individually and checked that I am still subscribed and that the bell icon is checked. I even responded to @FilmSensei on his channel and I know that he always responds within hours, but got no response. This was two days ago. It may be that I have accidentally clicked some setting or something, but I don't know what that may be. I wonder if anyone else has had this problem, or knows how to fix it.
