Prior to launching your changes to your users, there are steps your team can take to ensure the changes are correct before publishing. All changes you make remain in an ‘edit’ stage, until you explicitly publish them.
At the bottom of each column on both the Variables and the A/B testing tab, we have the ability to show this configuration on a Development Device. When you run this build you can link it to your profile in Leanplum. Then, whenever you select this configuration option we’ll immediately update your app to show you these changes. Then, when you’re comfortable with the change, you can click ‘Publish’ on the dashboard to put the change into effect.
