Google Reviews & Trust Seal HP

This app doesn't work at all, and you'll loose 10€ (exactly like me).
Please, Shopify, beware before to valid such an app on your store....

It does NOT work even after repeated information by the developer. The app only loads reviews once, so if someone else writes a review, it will never appear on the site.
Info from the developer is that we have to play the site in anonymous mode :( This is honestly the height of amateurism

UPDATE - Since March 2022 THE APP DOESNT WORK ANYMORE. All collected Google Reviews are GONE. Customer Support doesn't reply anymore. Great Customer Service. Installation and Customisation is very easy.
What I still miss is the customisation to translate the badge text but this is scheduled to be implemented by end Jan 2020. So now I hope customers will use the Google Customer Survey, so we have some reviews to show soon. :-) One comment regarding this 1 star review I saw:
The app is not for Google ads, so the reviewer seems he didn't read the what the App is for. GREAT SERVICE - The customer service was very helpful and helped us to find a issue we had (caused by us, because we tried to install the Google code ourselves before and had not removed it. Chandra from Meggnotec was able to find that code issue and help us to remove it. PRICING - What I really like is that this is a one time fee. I would not go for anything else. Very honest & fair!
