Summary
UTM Parameters Not Populating with Known People Form Fill
Issue
UTM parameter field values are not being captured for some people's form submissions, even though the form is configured to capture the values.
Solution
When a form is using the "Show Custom HTML Form for Known People", the submission button will generate a Filled out Form activity, but will not write any new field values.
When attempting to capture UTM parameters with the feature enabled, those UTM values, as well as the other fields on that form, will not be captured.
