Map proofing data with proof info columns is not available
I have an enterprise license and am the owner of the sheet. I want to map proofing data with proof info columns (per this article). I would like to do this so the team sees the proof status at a glance. I do not have the option "Create Proof Info Column" in the proofing panel, as the article states.
Am I missing something? How do I get this proof info column feature? I really need this feature to streamline the multiple approval processes my team has.
