helpme plis

Hello,

When I view that page on mobile, I was redirected to its mobile version here http://www.twaonline.com.mx/landingjump/phone/index.html. When I check its source code, I can't find any form while the problem is still occurring. In other words, I believe the problem isn't with the form at all since there's no form embedded on the mobile page. I suggest to check and review what's causing the mobile page to keep on jumping back to the top. I'm sure it's something to do with the scroll_wrapper body class where you can find on your website scripts.

The desktop version of the page works perfectly fine http://www.twaonline.com.mx/landingjump/index.html.

Thanks!

Sorry, I found the form on this page http://www.twaonline.com.mx/landingjump/phone/registro.html and it doesn't seem to have any relation with the form. Does removing the form on this page resolves the problem? If yes, please re-embed the form on the mobile page using only the iframe code below.

See if this helps. Thanks!
