Do I own this game or app????

Sounds like an Optical drive issue OP, where the disc drive doesn't recognize that a disc was actually inserted, one trick is to slightly hold the disc by the outer edges while the drive attempts to pull it in, then let go.

Often, this trick will suck the disc in a tad further thereby FULLY activating the disc inserted mechanism. If no joy, call support.

Important, never place a finger in the center hole of a disc while attempting to insert a disc. If your finger gets stuck in the hole of the disc while the drive attempts to pull it in, you could lose some flesh. Yes, I learned that the hard way. lol

This has happened to me several times too.

1. Make sure if you've installed the game to an external HDD instead of your console internal storage, that the external HDD with the game on it, is connected to your Xbox One.

2. Ensure the game or app is up to date, and that it has fully been installed.

3. Ensure your console has the latest system update.

4. Restart your console and try again if the above don't work.

5. If the above don't work, contact Xbox Support, the official support agency Microsoft has delegated. Don't rely and wait for the reply of unofficial non Microsoft employee/support people to make a reply. Xbox Support since I've used it, is great. Although
they're not perfect, it is the official support body from Microsoft. And Microsoft has quality control over Xbox Support and standards of what is expected from Xbox Support. Last time I contacted them, they sent me a feedback email for me to rate them on the
service. In 2011 I rang them and they read of a script which was funny but kind of weird. But now they have chat so it's usually txt chat.

Hi there,

please try the manual power cycle steps like mentioned on the following link, be sure to wait at least 60 seconds before powering on again:

If that fails please check what happens when you set the console as Offline and try to start the game to see what happens.

Let us know the results

Sorry to hear it. If you have the disc version of the game you will need to insert it to prove ownership. If you had purchased a digital copy of the game then you would not need to do this. As for the DLC please highlight the game on the Home screen and
press the Start button on your controller then select Manage Game. From there you can check to see if the DLC is installed to your console, if it is not you can go to the Ready to Install list in that menu and install the content so long as it was purchased
under your account.

used a download token to play the game yesterday and today it's asking if I own the game or app.

Might have to set your Xbox to 'my home xbox' in settings.
