We’ve improved the consistency of actions when moved or copied to another project. Now, when you move or copy an action to another project, any labels on the card will now stay in place — even if those labels don’t exist in the new project. They won’t be added to the project’s label list, but they’ll still show on the action card.
Assignees of the action will also copy to the new project. If the action includes assignees or placeholders who aren’t in the new project, you will receive a prompt asking if you'd like to add them.
