You're able to decide when you want Junip's review displays to show on your website to visitors.
This allows you to work on the displays in the background to make sure they look they way you want. It also gives you the opportunity to turn off your old review provider's displays before turning on Junip's.
When you're ready to turn them on, it just takes one click.
You'll want to go to your On-site settings and click the checkbox beside Enable on-site experience.
