Note about Google Analytics / Shopify Analytics
Due to the fact that the app is being loaded immediately after your store has finished loading, you will still see the visit of a blocked country/IP address visitor in your Google Analytics / Shopify Analytics dashboards and reports, but don't worry - all they'll be able to see is the blocked message.
The Country Blocker feature allows you to restrict and forbid the access of visitors from certain countries to your store.
After activating the Country Blocker feature, every time that a visitor will visit your store, their IP address will be analyzed using the services https://GeoJS.io
GeoJS.io is determining the origin country of a given IP address and returns the answer to the app.
If that origin country is in your block list - the access of that visitor will be blocked and the blocked message you have set will be shown for them.
