Set birthday date for old account

Hello, I have set instagram basic display api. And I have restriction app issues. When I try to retrieve user code, i have this issue: {"error_type": "OAuthException", "code": 400, "error_message": "Cannot access app due to app restrictions"}

It seems to be linked to birthday date which is not set because of I have an old account. But I cannot set my birthday date to this account. I saw this article but there is no entry for birthday date

Do you know how to set birthday date for old account ?
