I've been waiting for that feature way too long. It was clearly not a good communication exercise: Announced too early and missed too many release dates. I refresh my Teams daily to see if I am one of the lucky ones. But so far, nothing new.
Beside that, I looked at Project for the Web, because it has some additional features that our users are asking for. Saddly, it doesn't integrate with Planner and / or To-do. This means another place to manage tasks. A few more features but at the cost of integration.
Add Lists that are also being marketed as a task management solution and we are set to an even greater level of confusion.
Please make the To-Do / Planner / Lists / Project teams talk to each others and work together. Because, for now, it is easier to buy other companies solutions than to use the products that we are already paying for in O365.
