Offline mode is currently only available in the FooSales tablet apps.
The FooSales offline mode makes it possible to process orders via the FooSales apps without having to connect to the internet. Offline mode can only be utilized after you’ve logged in and completed an initial download of all your relevant store data.
All new orders, cancelled orders, refunds and product changes are stored on your device and can be synced with your WooCommerce database when you’re back online.
To enable offline mode, go to Settings and enable the Offline Mode setting. When doing so, a bar will display at the bottom of the screen which reflects the time the app switched over to offline mode.
At any time you can go back online by disabling offline mode in the Settings or by selecting the Go Online option in the bar. The app will then attempt to upload the processed orders and customer information to your WooCommerce store.
