We're launching a new way to deploy Optimize on websites. The new Optimize snippet will provide higher performance and simplicity than past methods. The new Optimize snippet, in addition to offering greater performance, will also provide an option to run in synchronous and asynchronous modes. With this flexibility, sites with ‘flicker’ issues can choose to run the Optimize snippet in synchronous mode to skip the flicker.
