As a store owner, you can decide whether or not you want to display the reviews received by your customers. Whenever a user posts a review on any product, it doesn’t immediately get displayed on the storefront.
You can see the reviews on the app dashboard; until you approve the review, it will not be visible on the storefront.
For manual approval of the reviews, navigate to the Reviews section; in this section, you can see the pending reviews; open them, and publish them at your convenience.
