We attempted to use this to help us with Bottle Deposits and Recycling Fees. When I noticed that the fees were not applying properly, I reached out to support.

I was told
"The order was placed from an older Android device (Android 10K, released around 2019).
Please note that the letter “K” in Android 10K typically indicates a customized or modified browser/WebView environment rather than a standard Android browser version. In such cases, the device may be using a custom or embedded browser, which can affect how scripts are executed.

This is a known scenario — issues may occur due to outdated or customized browser environments on such devices. Since our app relies heavily on JavaScript for validation and interaction, compatibility with older or modified browsers unfortunately cannot be guaranteed.

Shopify officially supports only the two most recent versions of major browsers, as outlined in their documentation"

This left us with a huge gap in being able to correctly use fees, and led us to move on to a different app.

It works in Canada, specifically for the Alberta import fees on wine. I had to call support because I didn't know how to test this. Support was responsive and pleasant.
