Why is my total amount of Diamonds not enough to claim the Diamond Purchase Bonus?

• Total Diamond Purchase Bonus
• Daily Diamond Purchase Bonus

Only Paid Diamonds count towards the campaigns above.
Both Paid Diamonds and Free Diamonds are treated as in-game currency, but the main differences between the two are as follows.

• Paid Diamonds
  • Diamonds obtained when a user has paid for them.
• Free Diamonds
  • Diamonds that can be obtained through in-game content, such as missions and boss battles.

The Diamonds that can be bought in a Diamond Pack are Paid Diamonds, and the Diamonds that are provided via the 1st Time Double bonus are extra Free Diamonds.
Therefore, these extra Free Diamonds do not count towards the total amount of Paid Diamonds needed for the Total Diamond Purchase Bonus or Daily Diamond Purchase Bonus.

Additionally, the time that each Diamond Purchase Bonus is refreshed is 0:00 AM (Server Time).
