+## Why do the "Modified On" fields of my records get changed when no changes are made to them?
+This can be caused by cascading behavior with the parent record. For example, when a case is assigned to another user. Refer to [Table Relationships](../data-platform/create-edit-entity-relationships.md) to configure this behaviour.
+
+## What permissions does timeline need to run?
+* To see attachments, you need read access to the "Activity file attachment" entity
+* For personal settings and bookmarks, you need read/write/create access to the "Custom Control Extended Setting" entity
+
+## How do I configure timeline for mobile offline?
+For general guidance on enabling mobile offline for your app, see [Set Up Mobile Online](../mobile/setup-mobile-offline.md) 
+The offline profile must have the **Note** and **User** tables in order for timeline to function.
+
+> [!NOTE]
+> Only notes are available when offline
