I received a message saying "sensor overheating or overcooling". What does this mean? How should I respond?

If you receive a message indicating that the sensor is overheating or underheating, it means that the sensor is unable to provide a glucose reading due to excessively high or low temperatures. Please move the sensor to a more comfortable environment and wait a few minutes before rechecking its status.
