Hello, I've created a popup which includes a MailChimp signup form, but unfortunately it doesn't display on mobile devices (tested on iPhone 6, iPhone 5 and iPhone 4s).
I've never had a problem before when using this plugin, so I wondered whether it's the MailChimp form causing the issue?
The page where the popup is (which displays after 1 second):

Thanks for your help.
