Hello and thank you to anyone who gave solutions to this problem, but I figured it out! After pressing the middle/B button to get to the clock and then changing the time to 9:59, 2:59, or 5:29, I always pressed middle/B button again to exit the clock but dont do that! After setting the clock don't press any more buttons, just wait. And yes the Matchmaker apparently will still come even if your are 10 years old. Thanks so much to anyone who posts about the Matchmaker, I never would have figured this out without your help! ~Note; this happened on a V3 tamagotchi.~
