Admin setting Issue(KOE004)

Getting following error :

Admin setting Issue(KOE004)

Confirmation from admin is required.

Hello

I think it will be solved by going to my application and activating Kakao login.

Thanks @tony.mb, now activation issue gone but getting following error :

AuthError(statusCode=401, reason=Misconfigured, response=AuthErrorResponse(error=misconfigured, errorDescription=invalid android_key_hash or ios_bundle_id or web_site_url))

Even after adding hash_key

Did you set key hash after looking at this guide?

If you set it right and still have an issue, please let me know your application id in Kakao Developers.
