When I click the RevMob ad banner I get the following screen. Does it mean it is working or not?
In Dashboard I generated with "On With Ads".
I have written this code for RevmobAds:::
[RevMobAds startSessionWithAppID:@"54b9fdbcf47abad967fa6530"];
[[RevMobAds session] showFullscreen];

Yes, it is working. "Test successful" means the code you have written is correct. If you still need more details, contact them directly.
