Recaptcha loading multiple times

Hello Takayuki,

We are using the Recaptcha v3 for our forms and loaded using the alternative recaptcha.net version as some clients are having problems connecting from China.

add_filter( 'wpcf7_use_recaptcha_net', '__return_true' );

Using some tools like GTMetrix and requestmap.webperf.tools The problem I see is the Recaptcha JS files being requested multiple times.

GTMetrix:

• https://www.gstatic.com/recaptcha/releases/5qcenVbrhOy8zihcc2axxxxx/recaptcha__en.js 162KB
• https://www.gstatic.com/recaptcha/releases/5qcenVbrhOy8zihcc2axxxxx/recaptcha__en.js 161KB

Request map:

Could it be that using the alternative recaptcha.net version loads the script twice? Any way to reduce the load?

Is there another spam service that works as good as recaptcha with contact form 7 and does not load too much JS?

Thank you. Have a nice day ??
