Ribbon on top of screen

there is a light blue ribbon on top of the screen saying that “we cannot reach the server to update your progress”. Does this happen to you?

It means your internet connection is disrupted.
You may refresh the page.

This is also happening to me. I’ve tried 3 different browsers and it happens on all 3.

This does not have anything to do with your browser, but we still recommend the use of the latest stable release of Chrome.

If you are seeing this notification, it is likely because the fCC servers are under high load, or your internet connection is being interrupted.
