Why didn't I get free premium after entering the invite code?

When the inviter has Special Reward Quota, the invited user has a chance to get free premium after installing the app and entering the invite code. Free premium is not available for all users.
If you didn't get premium, you can still use PikPak's free features as normal. Free users get 6GB of storage and 3 daily cloud download tasks. We hope these features can meet your basic needs.
