BTW, you can still see a full list of your client along dates of their last update, if any, by clicking on Intuit Link on the left panel.  Alternatively, you could see the latest activities from within the Tax Return by clicking on the "New" icon on the far right and that will bring up the drawer with all the contents within Intuit Link for that particular tax return.

It is not Intuit(ive) or user-friendly but that's what we have in Link at this point.
