SalesPop: Order & Sales Popup

I couldn't find out how it works.... How to integrate in my shopify shop?
How I can rate an App that doesn't work?

Ruim, dificil de mexer e ainda não entrega o prometido.

the app does not work. not letting me add custom sales and its not letting me toggle the switch on

This plugin didn't work for me.
Or I don't understand how to use them.
If someone know please contact me

This is misleading. The app description says "Free up to 1000 visitors/month" but then before you even start using it, it forces you to consent to some "up to $49/month charges" and explains that you're actually signed up to a 7 day trial. Not cool!

Uninstalling it! it doesn't let me use or create a sales pop up notification!

I wanted to try out this app first for free and see how it helps for my business but once i added to my store it forces me to go on growth and pay $999 every 30 days..must be some kind of joke..
