Can I promote my paid app? How do I get an icon URL for my Android App? How do I select multiple categories in Advanced Targeting Restrictions? Integration instructions say an App ID is required. What is this and how do I find it? What if I have an idea for an original ad unit? What is 'Customer Purchase Price'? What is an Android Package ID? What should I select for "country" when creating an iOS app? Why do I see NA as my placement name? Why should I add the Currency Redemption call if I only have non-rewarded placements?
