Ive test the video and ad banner in unity , everything works well . All Ads showing up when test mode is off.But the only ads doesn’t work is ad banner . Ad banner only works in test mode but doesnt work when the test mode is off. Is there any specific reason for that not working .
In some regions our supply of banners from advertisers is less than the demand from apps that have implemented banners. This means that sometimes there simply aren’t any banners available to show.
You can check if this is what’s happening by looking at the device log (e.g. by using Logcat on Android or Xcode on iOS). If you try to show a banner and nothing appears, you should see a “No Fill” error appear in the console.
