how Unity ads impression count works?

Hello! I’m just really new to Unity Ads and this will be my first release implementing it.
To prepare for release, I unchecked “enable test mode” and built my app and played it on my iphone.
after unchecking test mode for ads, I started to see real ads.
I think I watched around 20 ads while I was testing my build, but they weren’t counted as ‘impressions’ in my unity ads account.
I know my views for test purposes are not valid and shouldn’t be counted, but I just want to know if I implemented the ads properly so that the impressions will be counted when I actually release the app.
Maybe there a special algorithm within unity services that disables counts before release?

Dont do that and Stop asking this kind of questions, please

First release, with proper ids and wait 1 day, then ask
