Unity ads not working after change of account

Monetization & Growth Unity Ads
1

Hi,
I created a project with my private Unity account and enabled Unity Ads there.
Then I moved project to my companys account. Unity said that I have to create new ID for project, so I did it.
But after I’ve changed account ads are no more shown in editor nor Android device. Even on test mode. All buttons that launched Ad doesn’t do anything right now.

I didn’t change code. I double checked Project ID.

What should I do to enable Ads on second account?

I managed to fix this. My ads weren’t properly initialized.
All I had to do was to initialize ads according to this: Unity developer integration guides

Previously ads were working without this so I didn’t know that this was required.
