Hello,
We’re sorry to hear that you’re experiencing trouble with the payment and updating the PRO version. It seems like the issue might be related to the zip code. If you’re trying to make a payment from China, please ensure that your payment method supports international payments and that your IP is not a proxy or VPN.
If you’re still facing issues, we recommend contacting your bank to ensure that they approve the payment from your end. Additionally, you can also try using a credit card instead.
If the problem persists, please send us a screencast of the issue, and we’ll be more than happy to assist you further.
If you have any other questions or need further assistance, feel free to reach out to our dedicated support team here.
We’re here 24/7, 365 days a year to help you out!

Hello,
Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
Please ensure that your payment method supports the following:
– Payments in USD $
– Supports subscription-based payments
– You are not using a prepaid card
– International payments are turned on
– Your IP is not a Proxy, or you are using any VPN or hosting service
Also, please make sure that the flag during checkout is showing the correct country at the top right corner.

If everything from the above is enabled and working, you can also try using a credit card instead.
You can also call your bank and ask what’s stopping the payment from going through and request them to approve it on your end.
Looking forward to helping you.
P.S. Please send a screencast as well if the issue persists. You can use a tool like Loom.
