title: Microsoft GraphAPI users delta doesn't return "assignedPlans" property on subsequent calls
body: <p>When using the GraphAPI's Delta Query for <code>/users</code>, we have noticed that the <code>assignedPlans</code> property is only returned on the first call to <code>/delta</code>, but on all subsequent calls that use the <code>deltaLink</code> returned on the previous call, the property is consistently missing.</p>
  
  <p><strong>The API call we make on the first call:</strong></p>
  
  <pre><code>GET https://graph.microsoft.com/v1.0/users/delta?$select=id,mail,givenName,surname,userType,displayName,givenName,userPrincipalName,businessPhones,jobTitle,mobilePhone,officeLocation,department,companyName,assignedPlans
  </code></pre>
  
  <p>This call's response does include the <code>assignedPlans</code> property for users, but on subsequent calls (using the <code>deltaLink</code>) - this property is missing.</p>
  
  <p>Is this a known issue with the Delta Query?</p>
  
  <p>Thank you!</p>
