It seems that you cannot restore a Live version back to another Live version. Clicking the Live and then restoring will actual change the Development version it appears?
I’ve not yet used the restore feature, and I’m not sure what the intended behavior is, but FWIW, I’m not sure I’d want to overwrite the live version directly. I’d first want to test and verify functionality before pushing to live from the dev version.
Again, I’m not sure if that’s the intended behavior, but at the very least, better wording / explanation could be provided. I wonder what the docs say.
