I have a hard time figuring out how to correctly implement Unity Ads. At first, I use test id to test the ads and it works well. But when I switch to my own gameId, there’s no ads to show. I’ve published the app to Google Play and in my Unity Dashboard, it tells me that it has Ad Request but no impression. Then I try to debug it, I get D/unity banner: Placement banner could not be found in the log. I wonder what did I do wrong.
Many thanks to everyone who help this!
