Pricing not Updated to my Local Currency Rate

I was using the free version of this plugin before, but I noticed the premium version will allow my price to update automatically to my local Nigeria currency rate from USD. That is why I got the premium version, but the plugin still didn’t convert the Aliexpress USD rate to my local Nigerian currency. Kindly check and help fix it. I want the pricing to auto-convert from USD to NGN using Google rate upon product import. Thank you.
