After selecting a currency, it seems that geolocation stopped working
When you use the drop-down selector to choose a currency, the app will continue displaying prices in that currency:
The manually selected currency is cached for a couple of weeks to avoid bothering your visitors. Otherwise, they would have to select their desired currency over and over again.
For that reason, if you're traveling to another country, you may be mystified by seeing the previous currency instead of the geolocated currency.
If you clear your browser's cache, the geolocation feature will run again to select the most appropriate currency for your location.
You can also use the 'Autodetect currency' option to trigger geolocation again:
Please note that, depending on your configuration, this option may be read 'Clear selection', 'Auto' or 'Clear'.
Finally, you can always see the app converting the prices in your store from several locations around the world by using the GeoPeeker service at https://geopeeker.com/.
