Unable to add Planner app to Teams

[AndrasBotos]

Hi, 

We're in the process of setting up a new system for a new company, and this problem occurred.
We want to use Planner for tasks and Teams for communication. I'd like to add a planner tab to the general channel, but planner doesn't show up between the apps. 
Now I'm aware that it's not possible to add planner to private channels, but AFAIK our general channel is public. What could be wrong?

Thanks!

In order to add Planner to a standard channel you need to have two things:
1) The Planner app has to be allowed in the Teams administration console
2) The person adding the planner board has to have permissions to add Groups in the tenant.
If you don't have both of these things you will either not see the Planner app or you will see it but encounter an error when trying to add it.
NOTE: Planner is now called Tasks by Planner.

Hi @Karen_D17 
Thank you for your reply!

The permissions were alright. But your note about the name change was the key, because I didn't know about that. To be honest the name is weird and the logo is not even office like...
Anyway now it works, so thanks again!

@Karen_D17 - can Tasks by Planner be added to a chat that is not associated with a Channel?
