CORS Violation between Segment and Unbounce

I am trying to integrate Segment with our Unbounce pages, but keep getting a CORS violation from a crossdomain ajax request:

“Access to XMLHttpRequest at ‘https://profiles.segment.com/v1/spaces/L83unNzNMo/collections/users/profiles/anonymous_id:1a3c1bf9-319b-4283-9c11-990b4d0bf6e7/external_ids’ from origin ‘https://www.brilliantdistinctionsgiveaway.com’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.”

If it was Apache I know I’d be adding the policy to htaccess, but is this something that can be fixed in Unbounce?
