why we can not create planner plans for private and shared channels

johnjohn-Peter I would recommend leveraging Microsoft Teams as an integration point between private channels/channels shared across teams to enable seamless task collaboration. Specifically, Planner relies on a SharePoint backend site to store and sync task plans, which dedicated SharePoint sites are not automatically provisioned for private or shared channels. However, users from separate teams and channels could be added to a common Planner if a SharePoint site is manually created and connected. Also, presence indicators in Teams would reflect availability status across both private and shared channels.

Furthermore, by establishing Planner plans centered around shared projects, employees will have a built-in space to communicate task updates relevant to multiple teams and channels. Through thoughtful Planner set up, Teams can act as a conduit between previously disparate working groups.

Implementing select, purpose-driven Planner plans accessible by members of various private/shared channels can unlock improved task alignment between employees without compromising the segregated nature of those channels at an access control level.
