Please check if you have enough balance in your payment account first.

Google/Apple：
1.    If you cannot jump to the payment page, we suggest you try again after updating the version of Google/Apple Store. If the problem is still unsolved, we suggest you submit it in “Feedback” in the App with your frequently used email address. We will handle it for you via email reply.
2.    If you cannot complete the payment on the payment page, we suggest you consult the customer service of Google/Apple.

Bank card payment:

1.    Please check if your bank card information is correct and whether there is an international payment limit.
2.    If you were notified that this was a risky transaction when purchasing, maybe the reason is that you have tried to pay too many times today. We suggest you try again after 24 hours.

If the payment fails again, we suggest you submit your problem with the screenshot of failed payment via “Feedback”.
