 Custom Applications have the following limitations:
 
-## OAuth Scopes cannot be changed in the Ready state
-
-OAuth Scopes cannot be changed when a Custom Application is in the **Ready** state as it can be installed and used while in this state. You can change the list of OAuth Scopes assigned to the Custom Application permissions only in the **Draft** state when [configuring the Custom Application in the Merchant Center](https://docs.commercetools.com/merchant-center/managing-custom-applications#configuring-custom-applications).
-
-To change the OAuth Scopes:
-
-1. [Move the Custom Application to the **Draft** state](https://docs.commercetools.com/merchant-center/managing-custom-applications#moving-the-custom-applications-to-the-draft-state).
-2. Update the list of OAuth Scopes.
-3. Change the state to **Ready**.
-4. [Install the Custom Application](https://docs.commercetools.com/merchant-center/managing-custom-applications#installing-a-custom-application) again.
-
-<Info>
-
-When a Custom Application state is changed from **Ready** to **Draft**, it is uninstalled from all Organizations and Projects. Thus, when installing the Custom Application again, [Team permissions must be assigned](https://docs.commercetools.com/merchant-center/managing-custom-applications#assigning-team-permissions)  again.

-</Info>
-
 ## Project access is not automatically updated for newly created Projects on AWS
 
 When a new Project is created in the Organization, the Project cannot be accessed despite the **Project access** setting being configured to **Install for all projects of this organization** for an installed Custom Application.

+title: Improved permission management for Custom Applications
+description: Permissions of installed Custom Applications can now be updated.
+type: enhancement
+topics:
+  - Merchant Center
+  - Configuration
+---
+
+You can now modify the permissions of your Custom Applications in both **Draft** and **Ready** states, a feature that was previously limited to the **Draft** state.
+
+This enhancement allows you to make changes to permission, for example, adding new OAuth Scopes, managing permission groups, or removing unused scopes, all without uninstalling the application. With this update, all existing team permissions remain unaffected.
