Variant display, Currency Switching & Product Code

The issue is fixed in the latest version.
It's probably a different problem.

Did you configure the plugin API keys ? How do you know it doesn't work ?

Yes, I have the API key and inserted it into the module. When I go to the IP location site, it correctly identifies my location.

When I go to the dev web site (I cleared all cookies first), it shows the prices in USD which is the default currency rather than the currency of my location (which is both Displayed and Published under System...Currencies). Under the country in 'Zones' the correct currency is selected.

problem now resolved

What was the problem ?

I don't actually know - it just started working without me changing anything, so maybe there was something cached
