One further note: this issue occurs in Firefox (52.02). In Edge the system works.
Thank you for bringing this to our attention Michael. I wasn't able to replicate the error in my Firefox. I recommend logging out completely, clearing your cache and cookies, and then trying to access it again. If that doesn't work, private browsing may help (ctrl+shift+P in Firefox).
I'm glad it works in Edge. Chrome ( https://www.google.com/chrome/ ) may be another good choice.
