Sometime can be a login problem, it happens to me too to have an empty page. Try to close the browser and open it again.
Try a different browser or go into incognito.
It should work.
First check to make sure you are logging in with the right email address, in case you have more than one.
You can try clearing your browser cache and reopening in incognito/private mode.
You can also try with a different browser on your desktop or laptop.
