Product Price as per User IP Location

We have been using this plugin for a while but right now we have enabled USA and EU countries stores. We have also added pricing for different countries as below
1) Euro- Manually added
2) CHF – Manually Added
3) USD- Based on Eu Conversion

We have also enabled IP based currency. Now problem we facing is whenever user opens website from germany it shows them Euro which is correct, but it do product price conversion based on shop address which is Switzerland and shows price

For eg: Product 1: 249 Euro but first time when shop load it shows 225Euro which is conversion of CHF product amount
