Cannot enable Track Changes in Zoho Projects Doc

Cannot enable Track Changes in Zoho Projects Doc

From research, I figured that documents in Zoho Projects should have a 'Track Changes' option in the review menu. However I am unable to find this option in the review menu. See screenshot below.





This applies to any new documents created in Zoho or uloaded to zoho from Ms word without track changes enabled.

The option I have is to download the document, open in Ms Word, enable Track Changes in Ms word and re-upload the document. The track changes option is then enabled on the document, but I cannot resolve/edit/delete any comments added from Word in the document. Any changes tracked cannot be accepted or declined in Zoho. This needs to be done in Ms Word and uploaded to Zoho again.

Can someone let me know how this is supposed to work and how it can all be managed in Zoho?
