Currency not switching based on location, reverts back on shop page

So I just got this plugin and installed it.

I’ve set the auto changer on and told the plugin which currencies are to be used for which countries.

When I log onto the site, I get the site on it’s default currency which is GBP.

If I change my location via a VPN, it either doesn’t change at all OR it goes to EUR. The location i’ve change to is Denmark, so should be Danish Krone. I can manually switch but it’s not the point of the plugin.

Also even if manually changed to DKK, if I go to a shop or category page, the currency reverts back to GBP, and my selector only has GBP on it, I can’t manually change back to DKK.

Lastly, the exchange price is off. I just added something to my cart for £81.19, but when I change to DKK manually, it changes the value to 706.92 DKK, when according to google, it should be 679.23.

So please provide assistance for the geo-location issue, the selector not showing up and the inaccurate price rate.
