**Description**  
Hey, I have an iFrame set up for my webpage to pull in the webinar registration form. It works on desktop but on mobile, the recaptcha reloads multiple times as if the user is entering the code incorrectly. Therefore the user is never able to register for the webinar on mobile.

**Screenshots (If applicable)**

**Additional context**  
Please help!

Hi @storres we do not support the use of iFrames to contain registration pages (particularly because of some mobile browser issues), but this looks to be custom. Are you using the [Add Webinar Registrant API](https://marketplace.zoom.us/docs/api-reference/zoom-api/webinars/webinarregistrantcreate)? This would not require a recaptcha if you are handling the request.
