When changes become live
In Convert Experiments all the changes that you make in order to create the experiment variations are distributed through a content delivery network (CDN) in order to provide low latency to your visitors. By the nature of technology behind a CDN, it can take a while until the resources are being refreshed in case they change.
With that in mind, we have a maximum 5 minutes delay on the propagation of any change that you make inside your Convert Experiments application. Therefore after activating an experiment, editing any of the experiment's variations or editing goals it could take up to 5 minutes until the changes become live.
