Why can't my redeem code be redeemed?

If your redemption cannot be completed, please help to confirm the following points:

1. Whether the redeem code is still within the activity period.
2. Whether it is eligible for redeem code use (limited to new subscribers or free users).
3. Whether to repeat the redemption of other redeem codes.
4. Whether the redeem code is applicable to your region.
5. Whether the redemption times of the redeem code have been used up.
