How can I show ads in my app

how can I show ads in my app every 60 seconds?

yesterday i bought monitization extension , not showing ads even on guide . niethere companion work when testing online , seem waste of money to me.

I have to connect to a vpn to see my ads

2 days ago, I also bought monetization from Niotron Store, and it seems to be perfectly working.

I used it for admob component bidding with facebook. and the ads are showing in all of my apps.
