Really like the Share for Review feature however the interface differs slightly to exporting to pdf and sharing an online pdf. Having explored both ways to get client feedback on designs, although as the designer I prefer Share for Review (the ability to update the link with latest changes and being able to review comments direct in InDesign through the 'Review' tab), the clients find the interface on the online shared pdf easier and clearer to use and less buggy. Could InDesigns Share for Review have the same interface/features as the online shared PDF interface.
