Cannot revert to previous versions of cloud files

[markwm]

I want to revert to previous saved versions of my cloud files.

This seems no longer accurate, when I select a document. There is no version icon anywhere to be seen on my screen.

OS X, CHROME BROWSER.

Does your browser support scripts?

Which app was used to create the document and what file type is it?
