Update: Thanks for getting back to me. The app is now working and my products have been published. I will update this review with my experience using this marketplace.
----------- Original Review ---------------
*** This is a temporary 1-star review, to see if they solve my problem ***
I've paid 33 dollars and installed the app. After installed, I followed the instructions on their website, including the Mass Media channel on my products, but, every time I click in PUBLISHING, I receive the following message: 'Unable to import products'. I've contacted them through their website (they don't have a contact email or messaging service on their app), and here I am, still waiting.
Sorry for the publishing communication problems. We admittedly had an API problem with Shopify. The issue has been resolved and you can now publish and run campaigns as expected.
