This could be happening for a few different reasons. Check the following:

  1. Is your device connected to Wi-Fi? The outdoor readings are displayed via a Wi-Fi connection, so any network issues may prevent these from being displayed on your device screen.
  2. it is possible that there may be an issue with the data source that your device is following. If the station's 'last updated' time is more than eight hours ago, then this will have been disabled.
