Issue with Redeem Coupon Duplication

Hello, Currently, we plan to grant in-game currency to players using the "Redeem Coupon" feature. However, if we assume that we issue 10 coupons that grant the "A" bundle, players can use all 10 coupons simultaneously.

While we can validate the coupon contents to ensure that "A" is granted only once, wouldn't this render all 10 coupons useless?

I've searched the forum and read numerous posts on this issue, and it appears to be a long-standing problem without any apparent support or resolution. Is there something I might have missed?

I'll await your response.

Normally, one user can redeem infinite coupons. You can set limitation according to your needs. For example, you can write cloudscript and use a sign to validate whether this user had ever redeemed this kind of coupon, if so, return error and they can no longer redeem this kind of coupon.
