I have integrated MobClix to my app, the test adds are working correctly before entering my MobClix application ID, after giving actual MobClix ID i am getting below error.
( I have checked my MobClix applicationID, and also i have enabled only 320*50 add i used the same in code they are correct) Dont know why i am getting this error.
Error Domain=com.mobclix.ads Code=-503 "The operation couldn’t be completed. (com.mobclix.ads error -503.)"
