Gift Voucher App

[ANDYS01]

Hi all, currently MS is offering free $25 gift voucher, just wondering am I still able to get it if I have already redeemed the UK one? After the UK promotion, whenever I going to the gift voucher app try to redeem new promotion, but it keep showing the UK promotion code, does it mean I can not redeem anymore or I have to remove the credit from the wallet? I tried to do that but it says I have to clear everything? sounds like remove the account? can some people please help me. Thanks
