I'm trying to setup MobFox in Admob , ask me the API Key, I take the apikey that is on My Account / Account Information , but always gets the status of pending before the Admob and most times the apikey field is reset.
How do I proceed to setup the right way?
If you mean "Ad network optimization settings", yes you should use that.
If you mean AdMediation I believe you should use as Inventory Hash (former publisher id) which you will find at your integrity section of your ad on Mobfox. However I tried all options and still have pending in AdMob mediation report.
