I have a production account for my developerToken, clientId and clientSecret
and a test MCC Account with 5 accounts in child for my test.
I got the refresh token(offline type) for my test MCC account by oauth2 login and tried to get all account list under the logined user wih the refreshToken.
But I got only one account under the test MCC account.
I added another test account under the test MCC account but the result was same.
Why can't I get the all list of accounts even though I logged in with the test MCC account that can access to thier child accounts?
And I tried to logged in with the test child account(one of the subaccount) but I got this error message.
Thanks.
