Hi @managerslo,
I did testing with the latest version of Sydney. And I can confirm that while using Polylang, all slides text are translatable through Languages menu > Translations menu.
If you are using child theme or other mechanism to extend the default slide content, and this probably blocking Polylang translation, so you would need to do some adjustments. Refer to the relevant theme’s code in inc/slider.php. Sydney slide content can be found in these lines:
$titles = array(
'slider_title_1' => get_theme_mod('slider_title_1', 'Welcome to Sydney'),
'slider_title_2' => get_theme_mod('slider_title_2', 'Ready to begin your journey?'),
'slider_title_3' => get_theme_mod('slider_title_3'),
'slider_title_4' => get_theme_mod('slider_title_4'),
'slider_title_5' => get_theme_mod('slider_title_5'),
);
$subtitles = array(
'slider_subtitle_1' => get_theme_mod('slider_subtitle_1', 'Feel free to look around'),
'slider_subtitle_2' => get_theme_mod('slider_subtitle_2', 'Feel free to look around'),
'slider_subtitle_3' => get_theme_mod('slider_subtitle_3'),
'slider_subtitle_4' => get_theme_mod('slider_subtitle_4'),
'slider_subtitle_5' => get_theme_mod('slider_subtitle_5'),
);
$images = array(
'slider_image_1' => get_theme_mod('slider_image_1'),
'slider_image_2' => get_theme_mod('slider_image_2'),
'slider_image_3' => get_theme_mod('slider_image_3'),
'slider_image_4' => get_theme_mod('slider_image_4'),
'slider_image_5' => get_theme_mod('slider_image_5'),
);
