Chartboost ads implementation issue.
I am trying to add Chartboost ads to my game. When i try to generate the app, it says i have to enter the App ID into the Chartboost field in Services, otherwise i cannot click Generate APP. I created an app in Chartboost.com and copied and pasted the app ID and signature into GS services tab and wait for them to be saved. The problem is that i still get the message that i have to enter the APP ID into chartboost field and cannot click on Generate App. When i reload the GS publishing page, the Chartboost APP ID and Signature are gone from the fields i have pasted them.
What am i doing wrong?
