Must say I am disappointed.
There is always that missing 30% that make MS products a huge disappointment and makes them poor quality and inefficient to use. And so then unlike its been advertised, IT IS NOT A UNIFIED EXPERIENCE.
The premium planner plans & tasks can not be found in 'Planner', nor Microsoft 'To-Do'. None of the Premium Plans created or any converted Plans. So its rather useless.
Then there is the new Teams 'Planner' app. The suggested new way, maybe this works better? NO LUCK - The tasks from Planner Premium Plans do not appear in today, nor tomorrow or earlier nor anywhere else.
You can find the Premium plans you created or converted, and you can select one of them at a time, and use them in the Teams planner app.
But they are not available to your "My Day", Tomorrow, This Week, Future etc, etc, planning processes in any app method. So you can't include the task directly into your plans for the day to Unify & Keep track of the task coming in from everywhere and anywhere in the 365 environment.
There is one useless way around it - when a user/team member is assigned a task from within the project (Planner Premium), they get an email. So they can flag the email as 'today' for example & then the task is in your Day/Week etc planning process. It does work, but it's just a continuation of the reason to not use Project Online license - It creates another thing to do that we shouldn't have to do.
One great feature of Project is you can have duration - gr8 thing! But because of the disconnect between Project & every other task in the Microsoft Family, we can't bring that duration down to an individuals day or week plan. So we would have to get everything into project (Emails, Calls, Meetings etc) which is not possible. This is exceptionally disappointing that no improvements to this problem have been facilitated by this upgrade.
My last complaint on this subject - the none licensed users who access & update a 'Premium Planner' task from the emailed link, The expected Duration is locked for them - so If they complete it in 3hrs instead of 6hrs - this does not show as a great achievement by them, nor does it update the Timeline. They can leave a note or file explaining what really happened to someone who's role is to be caring for the schedule, But then is another task required of a middle person, to update & make adjustments to the schedule. This is not Automation, this further complication. This is another reason why it is worth only $2/month extra in it's current form. Let the non-licensed user update it in the task, and if it is a problem for some users, use an approval process for the middle person before the master schedule adjusts it's self...
Summary;
If they could UNIFY IT as we were led to believe would be the case, like PROVIDE ACCESS to Premium tasks FROM PLANNER APP & To-Do APP, + FREE UP SOME BASIC FUNCTIONALITY FOR THE TASKS FROM PREMIUM PLANS FOR THE NON-LICENSED USERS, it would be worth $10/month. Maybe we would be happy with $15/month.
Once again another promising product from MS that's proving a huge disappointment.
