Hi there! I'm here to help you with your issue logging out of the Sleep Number app on your iPhone. Let's work through this together!

First, could you let me know if you are seeing any specific error messages when you try to log out, or if the option to log out is not appearing at all?

While I wait for your response, let me share the general steps for logging out of the app:

1. Open the Sleep Number app on your iPhone.
2. Go to your Profile by selecting the icon associated with it.
3. In the Profile section, tap on the Account Settings icon located in the top-right corner.
4. Scroll down to the bottom of that page, and you should see the option to "Log Out."

If the option is not working or if you're unable to log out even after following these steps, let me know, and we can explore some further troubleshooting options.
