This post will walk through testing the Connection.Connected property in your PowerApps. If you are building a PowerApp with offline capabilities, then it becomes very important to test whether the device has an active internet connection. The sensor function Connection.Connectedcan be used to test for connectivity – if true, you are connected, false not so much. A common scenario is to check the result of this function in an OnSelect formula. If connected, write or submit to a live data source, if disconnected, write to local collection for submittal later.
