It may be that your Adsense account Is linked in the Ezoic Adsense account but hasn't pulled through to the Ezoic system. Which is needed for Mediation to complete.
If you are seeing the below for your Adsense link in Ezoic dashboard then this likely means Adsense isn't full linked in Ezoic. You can either open a ticket directly with the support team here, or if you are happy to share your Adsense Pub ID here i can take a look.
