Recaptcha not compatible with IE9?

Question

I'm trying to build a website working with IE9 and I must use a captcha to prevent scraping. The official recaptcha documentation is telling it should work with IE 10/9/8. When I try to load the recaptcha v2 with browserstack, I get the following message :

Please upgrade to a supported browser to get a reCAPTCHA challenge

If I try to load recaptcha's demo with Brave using IE9's useragent, I'm getting the same message, that's why I assume google is blocking recaptcha based on the useragent, but why is the documentation saying how to make it work on IE ?

Any informations on this ?

Thanks.

Please check the IE browser Compatibility View settings, and remove the google.com from Websites you've added to Compatibility View. More details steps, check this article.

Besides, you could refer to this thread and try to add below meta tag in the header part

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" >.

If still not working, perhaps the Recaptcha you are using not support IE9 version, you could try to update your computer to the latest Windows. See Microsoft’s instructions for getting Window’s updates.
