There's are two issues I am encountering, even after having installed the plugin update.
1. The draft does not save when I edit the newsletter layout (this has happened several times now)
2. The editor menu that should appear on the right is not there.
I don't think I have any other plugins on the list of known conflicts, the theme I am using is Custom Communities.
Please let me know whether these issues can be resolved, I have spent a lot of time on this now and will have to give the plugin a low rating if I have to give up. I'm sorry, I would rather not have to!
