Thank you for reaching out to the Community! I apologize but at the moment our survey invitation is not mobile responsive. I will definitely submit your feedback over to our engineers to review because we completely understand how important that is. Thank you!
Hello @TFRITSupport ,
The engineers are still looking into how best to revamp the current survey tool for modernity and mobile-compatibility, or integrate another survey provider into the system. At this time there isn't an update, but I've attached the feature request to your account so if and when there is one, they'll notify you.
