Currency Plugin not working with SG Optimizer even when excluding Home page

Hello,

Just purchased your Currency Plugin.

I am trying to use the Geo Location feature. I have SG Optimizer installed on my site. I have already excluded the Home page.

When I test the website with an IP Address from the USA, it will show USD.

But then when I refresh/clear my cache/browser history and then test my website with an Indonesian IP address, it still shows in USD.

I am using Sessions instead of Cache. I have attached the Currency settings below. I have already contact SiteGround and they said this plugin isn’t compatible. I thought the solution was to exclude the Home page. What other settings do I need?

Please help.
