I bought the plugin a few months ago, advertising for Android works as expected.
Now I publishing the project on iOS and there are difficulties. If you just download and throw Universal Mobile Ads and GameDNA in the plugins folder, the program packs the project without errors, but give a warning “Google AdMob SDK not installed!”. The app runs on a test iPad, but the ads don’t work.
If you successfully install the SDK through GameDNA, the packaging of the project gives an error at the compilation stage. You do not answer to my question by mail, I will ask it here. Please solve the problem, for more than 10 days can not complete the project and publish it on the App Store. details in the mail.
