That does sound like there's a crash when loading the editor, then. Can you confirm that you're on the latest iOS beta? I will have a thorough look through the code today to see if I can spot any issues, and try to ensure that if this is a crash that can be caught, that that crash is then logged.
So far you're the only one to report this and I've not come across it during my use or testing. Hopefully the issue will get resolved.
Sorry for the problems you've been having, but thank you for testing!
I'm on iOS 10 public beta 7. iPhone 6s Plus. The drawer where the "edit" and the "+" options are located will not load. It shows for a split second, then goes to the message "Unable To Load Word Art".
