title: Recaptcha V3 assets cause Pagespeed issues - how to defer
body: <p>We're currently using Google Recaptcha V3 across the public-facing portions of our site - while doing Pagespeed Insights performance testing (Mobile), Google themselves is reporting unused/undeferred CSS as a problem on their own Recaptcha css file:</p>
  
  <p><a href="https://i.stack.imgur.com/8H4ev.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/8H4ev.jpg" alt="enter image description here"></a></p>
  
  <p>Full resource address is:
  <a href="https://www.gstatic.com/recaptcha/releases/[...]/styles__ltr.css" rel="noreferrer">https://www.gstatic.com/recaptcha/releases/[...]/styles__ltr.css</a> (so it is clearly coming from a subsequent Google Recaptcha script request)</p>
  
  <p>We are including the original Google recaptcha script with the 'defer' attribute set - not sure what else we can do to cause this css to be deferred such that Pagespeed does not complain about it. Can't find any documentation on the Google Recaptcha site itself to help with this issue.</p>
  
  <p>Does anyone know how to defer this CSS to improve page load time? Not sure if this is somehow a Mobile specific issue, as Pagespeed doesn't report it at all on Desktop.</p>
