Problems applying InMobi ads in unity. First, I am Korean and I am developing in Korea. I wanted to apply banner ads and interstitials to my application. In the case of Interstitial Ads, when I put my Site Id, I get a gray background instead of advertising. In the case of Banner Ads, using Test Site Id provided by InMobi will normally display the test banner. However, when I put my Site Id, the banner does not pop up. All of the testing was done on a Tizen Z3 device from an Indian server using RTL services. What did I do wrong? I’ve attached the code. Let me know what’s wrong.
