title: What does notifyOnNetworkStatusChange do exactly?
body: <p>I had an issue where the <code>loading</code> property was not true when performing a <code>refetch</code>. I read somewhere <code>notifyOnNetworkStatusChange</code> to true would fix this.</p>
  <p>However we've notice after using this property we have some use case where we end up in infinite <code>refetch</code> loop with no good explanation.</p>
  <p>Can someone explain exactly what the <code>notifyOnNetworkStatusChange</code> do exactly on the useQuery hook? When should you use it, is there a particular <code>fetch-policy</code> you need to use in conjunction to it?</p>
