Hi, This is Hiten from KISSmetrics / Survey.io - We do not know what is going on with this and have not heard of this issue before. We're taking a look at this issue right now. At the moment, we think it <i>might</i> have to do with the Google Analytics code on the survey.io embeds, so we will be removing the GA code from them shortly. If anyone has any feedback or ideas please feel free to shoot me an email: hshah at kissmetrics.com
