I get errors trying to use my.1password.com

my.1password.com is broken for me.

After the interface opens, I get this error:
"Failed to load categories: Minified React error #136; visit http://facebook.github.io/react/docs/error-decoder.html?invariant=136&args[]=d for the full message or use the non-minified dev environment for full errors and additional helpful warnings."

After I click to make the error go away, I cannot get any of my saved items to display their contents - when I click on a saved item to select it, nothing happens!

At one point, I was able to see some items, but the one I wanted to display got an error message (don't remember the message).

Everything works fine in the desktop app (Apple iMac).

Please help,
Rich

P.S. The only category available in the dropdown list was "Mac Beta".
