A. To change the app language, go to your iPhone's Settings. Scroll down to 'General', then tap on 'Language & Region'. Here, you can add English as a preferred language. Restart the Trendyol app to see if it reflects the language change. If the app does not support English, consider using a translation app to help navigate the app until an English version is available.

B. If the app does not have an English option, you can use a web browser to access Trendyol's website, which may offer a better language selection. Use Google Chrome, which has a built-in translation feature that can help translate the page into English.
