I attempt to run the aip scanner from the azure portal and no labels are applied and this error appears in the logs: Value: Microsoft.InformationProtection.Exceptions.NoPolicyException: Label policy did not contain data, NoPolicyError.Category=SyncFile, NoPolicyError.Category=SyncFile Upon further research this error indicates that no label has been published. I can confirm that there is a label policy publishing a test label to several accounts including the aip scanner account. 

Is there something else I can check?
