With the changes to the Starter plan, we are no longer able to share Drafts with editor access.
I spoke to customer support recently about this (as I share many Drafts to my clients with editor access), and they let me know that if you upgrade to the Professional plan, it will allow you to again share Drafts with editor access.
I was unable to find any mention of this change in the pricing page or the blog post about the Starter plan changes. I think it needs to be made much clearer. But that’s the solution.
