Hello there @mauriciabad I wrote the following article explaning how to achive this behavior on dynamic pages with dynamic slugs in a Next.js project: Learn How to Internationalize Dynamic Routes Using Strapi and Next.js.
But if you want to use the same “slug” for different locales, you probably won’t be able to use the UUID field of Strapi, instead you can try using a text field, and then filter the record specifying the locale that user selected in your website.
