Issues related to forms.
I do not have any problem with the csv. I still use it. the problem may be that when you go to form advanced and then check on csv it wants you to name a .formdata.csv you save and publish it in public_html or on other cases htdocs ftp directory directly, the csv file name has to be the same as published and can not be in sub folders. if the email comes to you good then be sure that form data also comes for sure.
