A. To change the currency, go to your account settings in the app. Look for a 'Currency' option and select your preferred currency. If this option is not available, check if your account is set to a specific region that may limit currency choices.
B. If you cannot change the currency in the app, consider using the Trendyol website on a browser where you may have more options for currency selection. You can also use a currency converter app to help understand prices in your preferred currency.
