I followed the instructions for making two forms, by using a copy of the process file and renaming the form field ids. However I am getting 2 copies of each email submitted on the form.
Note: you can only see 1 form at a time on the page, because it is designed responsively. One form is shown for desktop, and then a different form is shown for tablets / mobiles.
I found this thread which is a similar problem, but I don’t think it applies to my situation?
