title: The service connection does not exist or has not been authorized for use
body: <p>I'm trying to create my first release pipeline, however I keep getting this error:</p>
  
  <blockquote>
    <p>Exception Message: The pipeline is not valid. Job Phase_1: Step AzureResourceGroupDeployment input ConnectedServiceName references service connection 
    which could not be found. The service connection does not exist or has not been authorized for use. For authorization details, 
    refer to <a href="https://aka.ms/yamlauthz" rel="noreferrer">https://aka.ms/yamlauthz</a>. (type PipelineValidationException)</p>
  </blockquote>
  
  <p>I've tried to follow the instructions in the link, however the "Authorize Resources" button does not exist.</p>
  
  <p>"Allow all pipelines to use this service connection" is already enabled and I have recreated the deployment task after enabling this.</p>
  
  <p>How do I authorise the resource? </p>
