I Can’t Invite Friends or Claim Rewards in PK XD Despite Multiple Attempts

I’ve been trying to use the friend invite feature in PK XD, but every time I attempt to invite someone, I receive an error message instead of being able to send the invite or claim the related rewards. This issue isn’t just happening on my account—my sibling is also experiencing the exact same problem, even though they just installed the game for the first time.

To troubleshoot, we tried inviting from a different device—our mother’s phone—without logging in, just to test if the invite system would work under different conditions. Unfortunately, nothing changed. The system still refuses to let us send invites or receive any referral rewards, no matter how many times or ways we try.

I’ve missed out on rewards that are part of an in-game feature I should have access to. This is frustrating, especially since the system seems broken across multiple devices. I’m requesting that the developers restore my ability to send invites and deliver the rewards I should have earned through those attempts. Please fix this issue as soon as possible.
