We have been receiving reports from customers that their websites are being blocked when end users are using Microsoft Edge in Strict mode. This is due to an incorrect tracker classification for some of Contenful’s domains (cdn.contentful.com). We are following up with the classification service owner to have Contentful domains removed from this list in order to mitigate this issue.
