How do you not get notifications??

So many times over the years I get messages from guys saying "I don't get notifications on this app" and it's been MANY different apps. I realize this is likely a ploy to get a girls number or something (which seems lazy, just ask) but is there any merit to this for men? Because IME you definitely get notifications unless you switch those particular permissions off in your app settings.

Idk, am I missing something else?
