Please check If you can't see anything on the Dashboard main page, you may be experiencing some displaying issues. These can be due to different causes, so the first thing to check is the zoom level of your browser and make sure the zoom is 100% or higher: normally, this may be visible to the right of the URL bar, or through the "View" section of your browser. We had some reports of browsers not displaying the main tab correctly for zoom levels under 100%. Most browsers allow you to reset the zoom level to 100% by clicking Control (or Command) and 0 (zero) or normally, this may be visible to the right of the URL bar, or through the “View” section of your .
If the zoom level fix didn't work, make sure you are using an up to date browser and try opening the Dashboard with another browser.
If the issue persists, report the bug directly from the Dashboard, attaching attach some screenshots and let us know that you have already tried the steps everything suggested here.
