"Your credentials have no profile to be processed" error message.
On your Amazon Advertising integrations page, if you see such an error message or a similar one next to an alert icon under the account name column, it may be due to the following reasons:
There are no advertising accounts tied to the connection you attempted making
The connection you attempted making is tied to an account type that isn't allowed to fetch data from the Amazon Advertising API
Our recommendation is to double-check that you picked the right account when making the connection.
