December 27, 2020 Review Updated.
The customer service came back to me and they helped me to fix an issue that I had, also they are super friendly and helpful.
This app does what it says and it's very easy to use. I also recommend getting the premium to have access to HTML, it's cheap and it's 1-time pay, differently from a lot of the apps here in Shopify, where they ask you to subscribe for a monthly fee.
Nice one. October 02, 2021
The app doesn't work anymore. It's keeping crashing and it's impossible to use.
