mobileCore Question!

Hello, I’ve just finished integration of the Admob Mediaition,

and this is the first time i’m trying an other network diffirent from admob, I want to know how often should I show mobileCore interstitials, and should I give higher CPM to mobileCore or to admob in the watterfall?

No one can tell you what will or won’t work. The best way forward for you is to experiment with those settings and see what works for that app.
We all have different types of users, apps and geos. For this matter we all have different results and different set ups that work well for us.
