## Key Benefits of Cache First

Check out some of the key benefits of Cache First.

- Enhanced Performance in Low Connectivity: Ensures smooth and fast app performance, even in areas with poor network connectivity.
- Faster Navigation: Loads data from the cache first, allowing users to quickly access the Work Order Overview without waiting for network calls.
- Improves mobile app performance on native record details and related lists screens.
- Seamless Updates: Simultaneously fetches fresh data in the background and updates the view if new information is available.

## Considerations and Limitations

- Cache First only works after priming is complete and for data queries from cache data.
- If the user hasn’t run priming in the last 7 days, this feature will be disabled until priming is complete.
- Cache First works for record detail screens and related lists, but doesn’t work for the schedule lists, LWCs, flows, or quick actions.
