Planner conversations and filtering issues

Hi Everyone,

I am really puzzled about Planner in it's current form and I hope someone here can point me to the thing I am missing here.

I have a big project on hand with a big team and I initiated using planners to get this sorted.
In the past I have used many solutions but since the company is Microsoft Foccused the Microsoft Planner seems the right way.

• Every plan I open starts with loads of completed tasks in sight.
  Of course I can filter them out, but besided the hassle of having to do that every time it also breaks the functionality of adding subtasks.
  I have to undo the filter, dive trough a list of stuff that's already been completed, at the subtask, reinstate the filter.
  We are talking about a paid planning solution here.....
  
  
• Secondly I can not get the task conversation to work.
  We used this alot before we had a premium subscription and now the function seems broken.
  I have been through the hassle of copying the planner and adding it to a new Teams channel, but still no dice.
  When I click the conversation button. Nothing happens.
  I tried opening the planner in the browser and making it link itself back to it's channel, but no dice.

Our fairly easy planning needs are resulting in loads of headace right now and I really hope there is something I am missing and this isn't just what it is..

Every tip wil be much appreciated.

Kind regards,

Karim
