In the current deployed version is not possible to import projects exported from other users. While importing from auto-exported projects works if you try to import a project generated from another user is impossibile to work on it and you just receive a grey screen.

Create a new project in a browser session
Export it
Try to import it in a different browser session
To simulate it just use incognito mode or try using two different browsers.
