For some reason my Illustrator library hasn't saved files properly a few times over the last week losing loads of work. I have Cloud Doc autosave set up for every 5mn and recovery saves every 30"... any ideas what's happening? There's nothing in my recovery folder and the files have been saved and closed properly.... Any chance there's file versioning in the cloud? (not seeing anything...)
I am afraid, this is not possible as of now. I will forward this feedback to the Product team. Also, I would suggest if you could also post it here (https://illustrator.uservoice.com/). This way, you will keep getting all the updates related to this feature and other users can also upvote, which would help us prioritize.
