Activity Log Missing Webpage Visits
We made some changes to our forms recently in order to use a single form along with multiple "thank you" pages. I'm monitoring the activity of these forms to ensure everything's working correctly, but I'm finding that some new contacts don't have any webpage activity logged before/after their form fill, while others do. This is making it tough for me to ensure our form changes are working correctly.
Here's an example of a new person whose webpage activity was tracked. I see both the page the form lives on and the "thank you"/follow up page were both visited, so I know this form fill worked correctly.

Here's a different new person who filled out the same form on the same page, but no webpage activity is logged.

Has anyone else seen this before? Thanks in advance for any feedback.
