Did you remember to [clean](https://www.fusetools.com/docs/basics/faq#upgrading-fuse) the project after updating?

A small reproduction of the issue, posted here in the forum, would be much better than _everything_ ๐
Have you checked whether the problem persists if you start a new project using fetch?

Thanks for the project. It does look like something doesnโt work quite right.
Weโll take a closer look and get back to you.

It seems like including JS files by using `` is not working anymore. We need to investigate this.
But it is an other way that I would recommend anyway. Remove the entries where you include JS files with `ux:Global` and include them in your project with Bundle instead, like this:
```auto
"Packages": [
"Fuse",
"FuseJS"
],
"Includes": [
"*",
"Auth.js:Bundle"
]
}
```
You can read more about this approach [here](https://www.fusetools.com/docs/fusejs/fusejs#importing-modules-by-file-name)

Did you remove the line in your MainView file? It worked when I tried it on your project I got from @remi.
