Thanks for putting this forward, John, and for the support, Jack. The timing was impeccable - we were pushing an app update over the weekend (to add support for delayed racking releases), so we’ve bundled this in at the same time. 
If you update to the latest version of the app now, the delivery instructions should show below the address on the screen for a delivery. The “Web view” button has also been changed to be a “View PDF/on web” button. Using this, you can still get to the web version of the delivery, plus you can view the invoice PDF and delivery note PDF. These can even be printed directly from your phone if you have your phone set up with a WiFi or Bluetooth printer!
We hope this proves useful
