I tried that but I got the invalid zip code error.
Hello,
Please make sure that the flag during checkout is showing the correct country at the top right corner.
If you are trying to validate data while accessing the website from a different location, you need to force the change of country in the dropdown.
Also, if you are using a Proxy or VPN, please disable that and use your actual ISP to update your payment method.
Let us know how this goes.
Thank you.
Thanks for your response!
That was very easy to miss, especially for users using an ultrawide screen.
I was able to upgrade to the pro version now.
