If you are using Elementor Pro or a different theme with customizable theme options, you may want to set a different logo per language.
Once you translate the logo, you may need to tell WPML which logo to display on the front-end in each language. You can do this by going to String Translation and translating the logo ID. If you cannot find the logo string in String Translation, you may need to click the Translate texts in admin screens link at the bottom of the page and add the text to the String Translation table.
