Description

---

📋 Steps to reproduce the issue:

1. Create a campaign with contact source as a segment (filter email not empty)
2. Add a condition "Contact device". Device OS- Mac, iOS, Chrome OS.
3. Add an action IF condition is True- Adjust points +2. If condition false- Adjust point -2. Publish the campaign.
4. Create a form with First name, last name, email and map it to the contact fields.
5. Embed this form in a landing page.
6. Copy landing page url and submit the form from another browser window (in incognito mode) or another machine (even better).
7. The contact gets added to the segment and hence the campaign.
8. Check event log of the contact.

Actual: Condition is false and points are deducted from the contact.

📋 Steps to test this PR:

Expected: Since the form was submitted from a Macbook, the condition should be true and points should be added to the contact.

1. Open this PR on Gitpod or pull down for testing locally (see docs on testing PRs here)
2. Repeat steps 1-8 from steps to reproduce.
3. Points should be added to a contact.
