Double check your preheat settings.
If your bed is set to "cool" or "no change," consider adjusting it to "warm."
Make sure your bed is plugged in to your surge protector, and that your surge protector is plugged into the wall.
If both are plugged in, plug another device into the surge protector to be sure it is receiving power.
Your bed needs a steady wifi or bluetooth connection in order to receive updated settings from your app.
See this article if you're having trouble connecting: "I am not able to connect to my bed."
You can run a quick test to make sure your bed is functioning properly.
See this article for how to run that test: "How do I run a Health Check?"

Restart your phone, and reboot your bed by unplugging it, waiting one minute, and plugging it back in.
