I was gifted a game and it says I own it but I have to buy it.

I would check and make sure that you got a gift code from the same region that you are in. Do you get any error codes about the region when you try to install it?

Remove your account from the console and the log back in and then

How to power cycle your console and network hardware:

Unplug the power cable from the back of the router, modem, or gateway for five minutes. If you have a router and a modem, unplug the power cable from both devices.

Restart your Xbox One console:

Press and hold the Xbox button in the center of your Xbox One controller to open the Power Center.

Select Restart console.

Select Restart.

Note If the console appears to be frozen, press and hold the Xboxbutton on the console for 10 seconds, until the console turns off. After the console shuts down, touch the Xboxbutton on the console again to restart.

After five minutes, plug the modem or gateway in first and wait for all the lights to return to their normal state.

If you are using a router, plug in the router and wait for all the lights to return to their normal state.

An try downloading it again.

Please keep us updated and let us know if you still need help.

The digital copy was gifted and the gifter is in the same region.
