Yes i created 2 accounts because it was not working, and it’s still not working with my account.
I have the same error, i tried with the others account and change my client id and secret id but not it’s not working.
Can you maybe delete the account with my adresse, and i’ll try again.
I have credentials (api_secret & client_id) for test, and it’s working fine with API request,
but when i connect to my account with this email, i have different credentials.
So I change it, and it’s doesn’t work, error: invalid_client.
If there’s two account on the same adresse, can you delete one account.
