title: App Service Plan doesn't allow VNET Integration
body: <p>I just created a new App Service Plan in Azure.  I picked the "S1 Standard" pricing tier and I went to configure VNET integration since applications running in this plan will need access to a database running on a virtual network.  I had previously done this exact setup in a different subscription.</p>
  
  <p>I've done VNET configurations dozens of times over the past year or two across different subscriptions.  But today, for this one, the <code>Setup</code> option for VNET integration isn't displayed:</p>

  <p>The link to manage existing VNET connections is displayed, but normally, when you're not yet connected to a VNET, the "Setup" option is displayed to allow you to create a connection.</p>
  
  <p>Is there a limit to the number of VNET integrations you can have per subscription?  Even if there is, I've got less in this subscription that I do in the other subscription and it worked in that one.</p>
  
  <p>Any ideas?</p>
