Why aren't Google ads showing up?

Question

Monetization

I have a site on ucoz. Decided to advertise from google adsense. Added a site, two days later it was successfully verified by Google. And now when I insert the ad block code, it is not displayed, instead of advertising, it's just an empty space. What could be the problem?
Help who knows, maybe. It's been three days (nothing has changed). tested with different computers and browsers.
