If you are not being able to redeem a code after typing it in, then here are a couple of fixes you can try to solve it:
1) Re-check if you have used the code
Lost Sword codes are limited to a one-time use. So it’s likely that you may have redeemed the a code and have obtained all the rewards from it. So re-check it and make sure that you are putting in a new code.
2) Check for code expiry
It’s also possible that the code you are putting in may have expired. So check our list above to see if they are still active or not.
3) Type in the correct format

4) Wait for bug fix
The redeem code feature may likely be bugged. So if you are not being able to redeem the codes after several attempts, it’s best to wait for a hotfix. The developers are on top of their game when it comes to fixing performance issues, so wait it out till the next patch.
