Your first questions

Will players be annoyed?

The ad sits in the scene and never stops the game, so there is nothing to close or skip.

Is my brand next to safe content?

Studios choose where ads can go, and campaigns can be limited to the titles that suit the brand.

How do I know it ran?

Delivery appears in a reporting view that updates in real time.
