Tango not opening.

Try these steps:

1. Go to your Microsoft Rewards Order History and open the reward details again. For the reward, select Order Details to get the redemption code or link. If needed, select Resend to send the confirmation again.
2. Try opening the reward from a different browser or a different device.
3. If the reward page still does not open, confirm whether the code or link is valid. If the redemption code is invalid, use the cannot redeem a code help flow.
4. If the reward is a non-Microsoft branded gift card and it still cannot be claimed, contact Microsoft Rewards Customer Support.
5. If the order itself may have been affected, check the order Status in Rewards Order history.

Common redemption issues can also happen if a VPN is being used, if redemption is being attempted outside the account region, or if phone verification is failing.
