Figma as single source of truth (designers, copywriters,dev workflow)

Hi, I am interested in how your cooperation with copywriters looks like.

On Figma (which is supposed to be a source of truth in our company ) we keep mockups with final copy for developers and then for testing.

I must admit that this workflow doesn’t really work for me - there are a lot of changes in the copy and even with small details I get requests for updates on the mockups. Previously, it was so that copywriters added changes, but it also worked on average because it was a mess in the files. How do you deal with it?

What kind of workflow works for you?
