If you're experiencing issues with internal links in your custom block theme built with ACF pointing to the original pages instead of translated pages after switching to 'Translate Everything Automatically' mode, this might be due to a known issue with link translation inside ACF blocks.

We recommend translating the links manually via the WPML editor. Ensure the link field is set to translate so you can manually adjust them. Alternatively, you can try the following workaround: make a small change to the default language and then re-translate the page. For more details, you can refer to our forum post here: <a href="https://wpml.org/forums/topic/i-need-help-with-translating-acf-link-field-in-advanced-transltion-editor/#post-16709536">https://wpml.org/forums/topic/i-need-help-with-translating-acf-link-field-in-advanced-transltion-editor/#post-16709536</a>.
