I have Office 2021 Professional Plus on my personal desktop but I can not figure out how to turn on the threaded comments feature. The only option I have is the old version "Notes" but I would like to be able to use the threaded comments when needed. I have checked the "Review" tab to see if I can "Convert Notes to Threaded Comments" but I do not have that option. I do not even have the "Show Notes" option between "Show Comments" and "Protect Sheet" on the Review tab, I do not know of any other way to enable threaded comments, please advise if there is another way to enable this feature or if there is something I am missing.
