Chartboost - delivering no impressions/ads on iOS version?

DigiChain

I've recently published a game with both Revmob & Chartboost interstitial ads selected (so that it will select one or the other at startup) but am getting no impressions from Chartboost. Revmob is working fine.

In my Chartboost dashboard I'm seeing figures for 'Installs', 'Bootups', and 'Uniques' - but yet it isn't delivering ads, but seems to indicate it's working otherwise?
I've double checked my service keys and they have been inputted correctly.

Have I missed something??.. (this is the first time I've used Chartboost in an iOS app).

you also checked the chartboost checkbox?
did you disable test mode on the chartboost website? (else it does it automatically after x impressions)
Did you test if they appear within your game?

Thanks BigDave,
I seem to have found my issue - the ad campaign was turned off!

Out of curiosity, have you played around with video interstitials? - and if so have you found them to be any good?
