title: Availability of Woocommerce Session after checkout?
body: <p>I'm currently using a Woocommerce session to save information that the user inputs on the cart page which affects a fee added to the transaction.</p>
  
  <p>I need to be able to access this information right after the order has been completed to make necessary updates to the user's account.</p>
  
  <p>I figured <code>woocommerce_thankyou</code> would be a good hook to use, but unfortunately the session only seems to be available half of the time.</p>
  
  <p>Are there any better hooks to use where I could confirm that the purchase had been completed and the session information would be available?</p>
