Yea! I'm getting notifications again!
I tried everything before. I was getting the notifications well past the time everyone else said they weren't, so when it happened to me also I hit "subscribe" first. That didn't work so I "unsubscribed" to everything then started over. That didn't work either so I went on the forum and tried suggestions from Nifty's thread
Bugs & Problems With The New Platform. Nothing worked but I didn't try changing emails like they suggested. I like my spam filters and don't want to have to monitor yet another email address so I figured I'd just give it time and they would fix it.
So far, yesterday and today it's working.
Hope they get everyone's problems fixed! I know they are working hard on it.
