Hello,
I found that you identify humans with Google reCAPTCHA.
This is a problem for users in the Chinese mainland: We cannot access
https://www.google.com/recaptcha/api.js .
So we can't pass the test.
But Google also deployed reCAPTCHA on another domain, and we can access it.
So could you change the domain for reCAPTCHA to
https://www.recaptcha.net/recaptcha/api.js ?
In this way, users in the Chinese mainland can also pass the test.
If you have set up CSP, remember to add
https://www.gstatic.cn/recaptcha/ to the script-src list.
Best Regards,
