Email Preview in Send Email Flow Step Not Working

Hello -

Is anyone else having an issue with the email preview not working in the Send Email flow step? It was working fine for us on Friday and then we turned on the Email Editor 2.0 over the weekend and today the email preview doesn't work.  I can see that is has "#EMEnull&isPreview" in the URL instead of the email ID.

I tried to read up on all the posts related to turning on the 2.0 editor and didn't come across this issue.

Thanks!

Carrie
