Neighbors app glitch, constant notifications

I recently installed an update for the Neighbors app (yesterday?) so I don't know if it caused a glitch, but I am getting constant notifications on this one post someone made about a lost dog, even though no one is commenting on it so the post itself isn't being updated so there's no reason to keep getting a notification. I can't find a way to turn off notifications for just one particular post, only to turn off all topic notifications, which I don't want to do. I get a notification on my phone every 5-20 minutes and I can't get it to stop. I even tried uninstalling and reinstalling the app. I have an Android phone.
