I've submitted a disavow file in my www version account, should I submit one in my non-www version account as well?

My non-www version account is my preferred domain. Should I submit in both account? Or one account will take care of the disavow?

We've done this on all disavows lately - submitted to both. We haven't seen any negative effect but we've seen cases where it SEEMS like there was a positive effect.  It's very hard to say because obviously disavows aren't instant and you aren't always 100% sure what you can attribute to which part of the process.

In my experience I would submit it to both.

I would definitely add it to both as Google sees these as two different sites.
