Hi, is this something that is coming on the SketchApp or is it not working?
I have done multiple version of the document but the Revert to → Browse All Versions… is disabled?
Hey @andrea84 
To discard something, are you working on Workspace documents? The Revert to option works in tandem with the macOS Autosave feature, which only applies to local documents.
If you are working with local documents (and the Autosave option is turned on in the Sketch settings), let us know, and we will troubleshoot your scenario together.
Cheers 
Hey @Diegogdag Ou yes I am working with the Workspace documents.
Is this feature coming on the Workspace documents? 
Thanks for the quick reply.
That explains things then @andrea84 !
If your goal is to keep clear “snapshots” of important milestones, I’d recommend manually saving a version whenever you reach a key point in your work (pressing ⌃⌘S). That makes those moments easy to identify later.
In addition, Sketch automatically saves your progress in the background as you work and creates versions for you. Even if you don’t manually save them, you can still browse them in the Versions tab in the Inspector.
So while the macOS Revert menu isn’t available for Workspace docs, all versioning is still there, just handled directly by Sketch 
Cheers,
