Screen is wrong.

It worked fine until this morning.
Suddenly I got the screen shown in the attachment.

• Change browser
• Change login account
• Try on Mac and Windows respectively
• Create a new app from template

I have tried all of these and all are in the same state.
How can I solve this problem?

I'm experiencing the same issue.

I just accessed it and it was fixed!
Was this a temporary problem? If so, I am glad.
