Hi,
The Basic Access Daily Reporting Quota error message you encountered is caused by exceeding the
daily reporting limit of 1000 daily reports for Basic Access accounts. Applying for standard access is correct as it is currently the only way to address the issue if you are required to generate more than 1,000 reports per day.
As for your standard access application, could you confirm how many days has it been since you've sent the request? Also, for us to investigate further, could you reply to us privately (using reply privately to author option) with your clientCustomerId?
Regards,
Ivan
