Refresh Icons and Functionality

What do the different refresh icons in the La Crosse View App indicate?

Refresh Alert Button

Displayed on device pages that have recently missed a regular communication; data will also appear in dark gray. Tap this button to request an update.

Red Refresh Alert Button

Displayed on device pages that haven't received an update in quite some time; their last received data will appear in dark gray. Tap this button to request an update.

Note:  Tapping these buttons may return the same result if the server doesn't have more recent data. Please verify a reliable network connection exists, check the sensor's battery status, and ensure the sensor is within range of a Wi-Fi display or gateway.
