Only "ask me again later" is the one that prompts you again. That's why I do mind that one, and appreciate the other ones.
Or have three buttons: “Yes”, “No”, “Remind me Later”. Apple does stuff like that in other parts of the OS, like when asking for app permissions, so they clearly know how to do it.
Yes, more text can be another way to provide the message, but if you've ever done any user testing, you'll know that people at best scan through your UI. I know I wouldn't read that, or at least would prefer not to have to read that.
I guess I don't see why "No" combined with "You can change this later in settings" is so much less offensive than "Not now".
