You can see the reason for the review outcome on the monetisation tab in your dashboard. The review team will review sites based on the Ezoic requirements here: https://support.ezoic.com/kb/article/getting-started-ezoics-requirements
Unfortunately, there are many great sites that we cannot work with for various reasons, as there are many different conditions that have to be met before we can show ads on a site. Even if a site has Adsense this does not mean it will meet the requirements for the platform. The review team will look at Ezoic requirements and Google Content Policies. Common reasons when there is no option in your dashboard to reapply your site includes:
Adult / Sensitive Content
Download / Streaming Websites
As a Google certified publishing partner, Ezoic must uphold the same content policies even though your status with Ezoic is not tied to Google. Unfortunately we cannot provide specific information on why sites are not approved for Ezoic’s platform. For additional information, please see the Ezoic Platform Requirements and Google Content Policies.
If you believe you have resolved and changed the site so these requirements are met the best thing is to open a ticket with the team. You may need to do this by going to the help centre Get In Touch, If you cant open a ticket go to the cant login in option and open one there without putting your site name in the field.
