The Issue

When logging into the Expression app you are presented with the alert message, "Device Offline". When the device is offline, returning guest, city, and start auto-population, and credit card memorials will not work. If using the registry in offline mode, all guest entries will be stored locally on each iPad and will need to be refreshed/uploaded (See Refresh App) to the dashboard when a data connection is established.

The Reason

Your iPad does not currently have a live data (internet) connection. There are a few reasons for this, either the iPad lost connection with Wi-Fi or cellular network, or the data connections are turned off in iPad Settings. There is also a possibility that the internet connection to your wireless router is down.

The Fix

Make sure you have a data connection (See Expression Service Selection > Types of data connections). If you are not connected to Wi-Fi (See Expression Setup List Step 1 > Connect iPad to Wi-Fi) and do not have cellular coverage, you will need to be connected before being able to pull new service data.
