Price changes from a browser to another!

This issue is getting on my nerves a lot!
For starters, I have a one page store with 4 packages in that page, like subscriptions. What I wanted is to display the price depending the visitor’s country currency (which is what everyone else in here wants). So I did all the setup a step by step and it was working in the begining. After a while I noticed that the visitors (who are from turkey) sees the price in USD. So I started checking again and now it is a mess, when I test it changes from a browser to another and even when using vpn it doesn’t work sometimes even though I checked the ip location which was correct (from turkey) so vpn is working just fine.

I even deleted the cash and history and everything else and still the same issue, and now, when I test on opera it displays a currency, and in chrome or brave it displays another! I am truely getting fraustrated with this! Can anyone please help me with this !

Ps: Everything is set, Maxmind subscription, Turkey pricezone, …etc
