Can not enable Email usage of User management

In my Kakao developers page. In the User management section, I cannot get to enable the “Email” information section
Is there any step I should do before they let me enable that section ? Many thanks !

@phungta Unfortunately, I couldn’t reproduce it.

But you can only enable the email field with “Select” option before your service is reviewed.

If you would like to enable the “Required” option, you need more processes at https://business.kakao.com/sync/ .

PS) You need documents in English?
