The Sleep Aid content available in Pillow is hosted on external servers, except for a few sleep aid tracks that are bundled inside the app.
To play any Sleep Aid tracks, Pillow must first download them using an Internet connection. Once the sleep aid track is downloaded you can listen to that track offline.
Pillow can download content either using Wi-Fi or Cellular data.
Here are a few things to check:
1. Make sure that your device can access the Internet via Wi-Fi or a cellular network
Wi-Fi:
Open the Settings app on your iPhone or iPad
Make sure Wi-Fi is turned on and connected to a network
Cellular network (if your device supports this)
Open the Settings app
Go to "Cellular" > Make sure "Cellular data" is turned ON
Scroll down to find "Pillow" and make sure the switch for Pillow is turned: ON
Once you do either of the above launch Pillow and try accessing the Sleep aid tab again.
