They also keep adding new stupid in-app notifications (I have OS notifications blocked for them) which ironically you have to use the website to disable. "Trending" stuff in subreddits you're not even in and suggested subreddits and garbage like that. I assume that rubbish does become an OS notification if you let them.
Those kind of “nagifications” are among my biggest pet peeves on the modern internet. Almost every social platform these days abuses the notifications icon to show you a bunch of not-actually-a-notification garbage to boost your engagement. LinkedIn is especially egregious in this regard.
reddit notifications are useless now. I do use the app but all notifications are off. I only look at that in app notification thing if I recently posted and am expecting replies.
