Cookie Needed To Link Form Submissions Isn't Being Sent

[dp1911]

Hey!

I have a webflow website using external forms. I've followed everything exactly in terms of connecting the forms to Hubspot. I have tried having them connected via the tracking code, and the Webflow -> HubSpot app, and we are still seeing this error:

It doesn't happen with every submission. Maybe like once every twenty submissions.

Everything I'm finding says I've already completed the set up properly, but if that were the case, we wouldn't be continuing to experience these issues.

I've also found examples of people using PhP to connect external forms (likely on WordPress). Will I basically need to write some JS to fetch and pass the cookies to HubSpot then? Via hidden input field, or?

Thanks!

I'm curious if you found a solution for this. We're running into the same issue with our Webflow Hubspot form integration.

It mainly happens when an existing contact tries to submit multiple forms that add/change various properties on their contact record.

The team thinks it is an unrelated issue, but I'm not so sure. I just want to get this issue solved ASAP, so any help would be greatly appreciated!
