Where is the Opt-In Custom Field on Web To Lead form
I've read https://support.insight.ly/hc/en-us/articles/360004027894-Tracking-opt-in-choices-for-your-contacts-and-leads and https://support.insight.ly/hc/en-us/articles/204248000-How-to-create-a-Web-to-Contact-or-Web-to-Lead-webform
But I don't see the custom field when I go to create HTML for my website in the Web To Lead section. Am I supposed to have this option or do I have to now manually write the HTML for the field?
Then I found this https://support.insight.ly/hc/en-us/community/posts/202808214-Web-to-Lead-Forms-Custom-Fields-Please-?input_string=Where%20is%20the%20Opt-In%20Custom%20Field%20on%20Web%20To%20Lead%20form which indicates the feature was added in 2016.. so where is it? Was this removed?
