Not getting notifications

Jennifer • Had baby girl
I'm not getting notifications in this app. I've posted a few times to the community and I'm not getting any notifications if someone responds to my post. I wad trying to look up a few past I had posted recently but can't find them and I never got any notifications if anyone responded to them. I posted a post today and have had two responses but didn't get any notification of the responses. PLEASE HELP. I've checked my settings and my notifications is on so I don't understand. Thanks in advance
