Cart simulation failed: Could not validate nonce

Hello @alexli126

Nonce?validation is a security feature and happens in many different parts of the plugin. Sometimes, this can be related to caching, but normally this should not be a problem that causes problems with payment itself.

You can try to reproduce the issue using a sandbox account, but please note that the results might not be consistent. This is likely due to varying parameters in the client’s browser.

If you have any further questions or need additional assistance, please feel free to contact us.

Kind Regards,

Krystian
