The reviews will in no way get displayed when they are not approved. Maybe, as a Admin you could see it, but it would not be displayed to a non-logged in user if it is not approved. I have also tested it in our local once to confirm it.
If that’s the case on your end, can you please give me your website details and temporary admin access to your site so that I could have a look at this and fix it straightaway for you? You can send us your details by creating a ticket at pauple.freshdesk.com
I hope you would be willing to reconsider the rating if we were able to sort it out.
