We now pull an additional dimension from AppsFlyer into Funnel. You now have access to http-referrer under the raw data reports.
Providing that you've connected a raw data report to Funnel, no action is required in order to obtain data from this dimension going forward.
You can learn more about the data you can obtain from raw data reports in this article.
We hope that you find this new field useful. If you have any questions, please contact email@example.com and we'll be happy to help :)
