Notifications

Please please please! Fix the notifications. It's starting to get really frustrating that it's not even working. I will occasionally get notifications from people post on other posts. However, I hardly ever get notifications from people posting on MY OWN posts. I use this app to get quick advice/imformation and I never seem to get it when I need to simply because I never receive the notification that someone has posted on my posts.  So please please can we fix this?
