@Galmis yeah in pre 2025-10, your extension and all of its screens was mounted within a single JavaScript worker. Now, when you navigate, each screen is mounted in its own instance. This was unfortunately a trade off we had to make to be aligned with the Web Standard Navigation API. However, you should still be able to subscribe to the navigation current entry and pass data in there. We are working on a better solution for you to be able to subscribe to changes in other screens, cross instance (worker). ie your Screen 3 would be able to subscribe to changes that happen in Screen 1.
