title: Purchased App in W10 Store remains in trial expired mode
body: <p>Some customers are reporting that our App in W10 Store remains in trial expired mode even after purchase. THE  warning dialog is given by store itself, we do not have any STORE API implemented in our legacy app.</p>
  
  <p>How to fix?  Nowadays store limits itself the trial period, there is no code needed to app for that.</p>
