i just found out myself helpless when i changed the ad type in my app from banner to interstitial
. But i used the same ad-banner
id from admob. though the interstitial are appearing just fine, my ecpm is quite low....
i tried to edit admob adunit type from banner
to interstitial
for my app but it is disabled under my app setting
tab.
so do i have to create a new adunit id
for my app and post the new version
of my application in the App Store
with updated ad unit id?
