I followed What would you like to change about the moderator election process? for a while, but the notifications blew up my inbox, so I unfollowed it. I can't find the exact time I unfollowed it, but it was probably Feb 2nd. After that, I stopped receiving notifications of comments posted under my answer. I am receiving notifications for other posts. I am still receiving reputation notifications for that answer.
I'm a bit slammed right now, so haven't had time to try to reproduce it and narrow down why there's no notifications for the couple of comments that happened 2 days ago in my inbox. It's possible I've mistakenly assumed this is due to me unfollowing the post, and there's some other cause. I've looked to see if there's a duplicate, but couldn't easily find one.
