title: In-app purchases won't load for MessageExtension
body: <p>In Xcode 11 I created standalone iMessage app File, New, Projects, iMessage App. Then I got two targets. AppName with product identifier: com.AppName, AppName MessagesExtension with product identifier: com.AppName.MessagesExtension and Enabled IAPs.</p>
  
  <p>In App Store Connect I created new app My Apps, +, New App. Where I selected following bundle ID com.AppName.MessagesExtension and added IAP Features-In-App Purchases with product ID: Example.</p>
  
  <p>Then I added in-app purchase Example to com.AppName.MessagesExtension, but when loading IAPs it says IAP not found. </p>
  
  <p>I have tried to change product ID <a href="https://stackoverflow.com/questions/39358743/imessage-extension-and-in-app-purchase">here</a> of IAP with no help.</p>
  
  <p>IAP code is fully working in another app (not standalone iMessage app)!</p>
