We load the registration pages in an iframe to enable us to add various tracking.

On desktop it works fine, but as of two days on mobile it doesnt - everything displays fine but the CAPTCHA fails every time, it just reloads and changes and then right at the top of the iFrame is an error message saying the characters were wrong.

We’ve got lots of people complaining about this.

Hi @TCADeveloper from what I understand, many of these pages are not intended to be used within iFrames, so that may not always guarantee support. Can you provide details on the mobile browser used?
