I've searched on google and using this forum's search but have come up blank on getting Known-Visitor custom HTML working on an external (wordpress) landing page. Basically, the known visitor custom html is not showing up in any browser (I tried chrome and IE). Progressive profiling is off. Form prefill is on for all fields.
Here is an example: https://www.datavisor.com/resources/special-reports/Fraud-Index-Report-Q1-2019
I'm already aware of the bug where if first, last, and email are not filled this won't work, but we are collecting all 3 of these fields. Any help here is much appreciated!!
