Sometimes my notifications take a while. If you close the app and bring it up half an hour later does it notify for the replies?

Your post also got posted 10 times. Would you mind removing the duplicates?

I don't think I've gotten any kind of screen notice either, or are you talking about after opening rhe app? Is it even a thing to show up like when you get a text/email? There's also an option in there to send notices to email if that's the kind of thing you want.
