Thread Title ... Why is Upwork Loading an Affiliate Network in my browser?
That specific redirect should only appear on affiliate referred traffic. If Upwork is loading an affiliate network, that would be because a person clicked an affiliate link directing them to Upwork.
Could you please share more information about how you were accessing the link so we could investigate further?
