What works offline in the Field Service Mobile app?

The Field Service Mobile app supports offline capability for technicians in areas with poor or no connectivity. Offline-supported actions include: viewing and updating Work Orders and Service Appointments, accessing and updating Work Order Line Items, viewing installed Products/Assets, logging Products Consumed, capturing signatures, taking and attaching photos, viewing Knowledge Articles (if pre-synced), and completing Time Sheets. Actions that require online access include running optimization, querying non-cached records, and Salesforce Flow actions. Data entered offline is stored in a local database and synced automatically when connectivity is restored, with conflict detection.
