exact keywords not showing up when exactly searched

So I've set up all of the campaigns types(discovery, generic, competitor, brand)about 18 hours ago, and there has been 0 impressions for every campaigns except for Discovery Campaign's Search Match. FYI, currently:
  • Manual keyword set ads are running 100%(not paused or anything),

  • nor any problem regarding the payment.

To test out if the ads are running properly, I've tried:
  • typing in a very specific exact match keyword(one that one one else would search up) from my Brand Campaign keywords but it doesn't show any results(shows "No Results") when it should be showing my app on ads if not organically.

  • clicking on one of my ads with my phone several times, but the new statistic wasn't applied.

Is there a way for me to check if my keywords ads are working as they should be? I hope I'm simply being too desperate.

Thank you.
