Hi, Miltos. The currency reporting is a Google Analytics setting. You can change that by logging into your Analytics account, clicking Admin, navigating to your store's view and hitting View Settings, and changing the setting titled "Currency displayed as".
I followed these exact instructions but for some reason, it does not allow me to change the currency settings. The drop-down is there but when I try to change it does not react. Do you know if there would be any reason why I may have a restriction?
Also I believe I've done all the right settings yet none of my sales are showing nor any of my goals.
Sorry I know that's a couple of questions in one but perhaps you can help
