Shoplift ‑ A/B Testing

I would stay away from using this software; their business model is like a trap, and without giving you any result, it just keeps asking you to upgrade for no reason. I feel like playing with those machines in Las Vegas and never getting anything after putting a lot of money. I don't know how Shopify allows this to be here.

I uninstalled the app within the free trial period yet I have been charged for the entire month. This is absurd

The plugin is decent but is throwing 502 bad gateway today. Not able to access the dashboard at all!!

The app didn't work - suddenly couldn't open the app after it froze when I clicked start the A/B test. Went to page "502 Bad Gateway: Microsoft-Azure-Application-Gateway/v2". Had to uninstall, quite disappointing because other reviews said the app was awesome.
