Ads not running when they're supposed to

I scheduled ads for my game about a week ago. They were supposed to start earlier today, but for some reason they still say ‘scheduled’

(it is 12:33 at the time of me writing this and the timezone is correct.)

is this happening to anyone else and if so, how do I fix this?

Are you sure the timezone written there is yours?

yes, I googled GMT +10.00 and it corresponds with my time right now

oh wait nevermind im stupid, its 11:59 pm not am
