license to access Planner Premium from Power Apps

There are two licensing layers: Power Apps and Planner features. The Planner and SharePoint connectors are standard, so those connectors alone do not make an app premium. However, if premium-plan data is accessed through Dataverse or another premium capability, the app can be designated premium. Check App details in the maker portal. If the app is premium, every person who launches it needs a Power Apps entitlement, including users who open its SharePoint portion. Planner licensing is separate. Microsoft 365 Planner rights provide basic editing in premium plans, while a Planner premium subscription, such as Planner Plan 1, is required for premium features. Therefore, administrators and senior users need Planner Plan 1 when using those features, plus Power Apps Premium if the app is designated premium. Power Apps Premium does not replace Planner licensing. Separating SharePoint-only and Planner-premium functions into different apps may avoid unnecessary Power Apps Premium licenses.
