Is this a problem for people who are the "Primary Admin"? I am having the exact same issue, the item was there and happily used!! Now is isn't there... I click on "getting things done" and no Tasks appear.

My partner sees it from his user login "Company Admin"  but I just don't have it on my login. I've tried from multiple PCs, multiple browsers, (cleared cache, etc.) Just seems my login doesn't show Tasks.  

I discovered I can get to my recurring templates by going to: Gear icon > Recurring Transactions > Reminder List. So at least that is something. But that losing a function from my workspace certainly sucks! Especially because others on my team still have this capability.
