Just checked it. Works as usual. So I assume something’s at your end.
You can try signing off then on again.
If doesn’t work try restarting the browser then sign off and on again.
If that doesn’t work try restarting your computer and sign off and on again.
As a last resort try emptying browser cache if you can afford that and sign off and on again.
Also alternatively if you can trying the above steps with another browser also might be worth trying maybe some update to your current browser or one of its add-ons did something.
If nothing else works I think there is an email address for the support as well which creates a support ticket so can create a ticket that way and receive and reply to support responses in e-mail until the situation is figured out.
