Well, it seems to be a bug with IndexedDB or the Localforage library in my code. Because in the site that is showing old content, the App.js it’s correctly updated (I made the mistake of thinking that no), but the data that the React App manages it doesn’t corresponds with the database that I can inspect with the Google Chrome tools.
So something in my code is causing that the previous builds don’t update the client indexedDB, and when I clear the cache, indexedDB it’s also cleared so the web content is updated.
Sorry for bothering you.
