Hey guys I've figured out how to fix mine! What you do is sign in on a browser and click on notifications there. There's an option at the top of the list labeled, "settings". There's a list of boxes that shows and you can check to allow certain notifications to show up in apps and mobile devices- the third column of boxes I think. Save the changes made and you should start seeing replies and what not. Hope this works for you guys! I can see you guys replying to my post now!
