Ready to download not showing

check your order history to confirm the purchases at https://account.microsoft.com/billing/orders/

if everything is showing there, find the game in the store and see if it has an Install button.

hope this helps.

Make sure you haven’t accidentally ‘hidden’ these games.

To keep your Ready to install list pared to the items you’re most likely to use again, hide the ones you don’t want to see:

1. In Ready to install, highlight a game or app.
2. Press the Menu button on your controller.
3. Select Hide from list.

To unhide items, go to My games & apps, press and hold the left stick on your controller, and then press the X button. To re-hide an item, repeat these steps.

To reinstall a hidden game or app, simply unhide it and then install from Ready to install. Or, you can download and install it again from the Microsoft Store.

This happens from time to time, try restarting the Xbox or signing out and signing back in again, or waiting a few hours can usually fix the issue.

you can try
power cycling your Xbox One and see if that resolves the isssue.

Highlight the game and press the menu button and then go to manage game. The Automatron DLC should show as ready to install. Choose that option and download the 1.1 GB DLC. Download content doesn't show under Ready to Install, only full games are available
there.
