@Emi_3 The rule that you’ve added in the _redirects file is for when the output is a Single Page Application (SPA), and is to ensure that any routes which don’t actually exist as files, are served the main index.html file.
You can tell it’s not working though, since you’re getting the standard Netlify 404 page, and the reason it’s not working is due to where the file is placed. You have the _redirects file in the root of your repository, but it needs to be in the folder that you’re deploying, in this case /dist/.
Additionally, you can see that your build doesn’t produce a logged-in.html file…
So once you move the _redirects file, (which you can do however you would like with Parcel, or by using a copy command after Parcel has executed), I would expect that what you would find accessing the /logged-in.html path would return the contents of the /index.html file… which is likely still not what you want.
