Switched back to iOS this year. Totally dumbfounded siri doesn't work with Maps, Outlook, Spotify or any of the other popular apps. That and Siri confusing 'four' with 'for' all the time ('set alarm 415' sets an alarm for 3PM) make it basically unusable.
Have you tried "set an alarm for 415"? That should disambiguate that you mean "four" and not "for" the second time (tried that a few times, not sure if it's the extra "for" or that it makes me clearly enunciate "four")
