Most of the sleep aid content in Pillow is hosted on external servers, with only a few tracks bundled directly into the app. To play a track, Pillow first needs to download it over an internet connection. After the download is complete, that track becomes available for offline listening. Downloads can be made using either 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.
2. Make sure that iCloud Drive is turned on for your device.
Open the Settings app for your iPhone or iPad.
Tap on your name at the top.
Go to "iCloud".
Make sure that the switch for "iCloud Drive" is turned ON.
Go to "Settings" > "Cellular" > Make sure "iCloud Drive" is turned ON.
3. Check your date and time settings.
Open the "Settings" app on your iPhone or iPad.
Go to "General" > "Date & Time" > Turn ON "Set Automatically".
4. Check if the services used by Pillow are blocked.
Pillow hosts its content on Apple's Cloudkit servers and Amazon's S3 servers. In some cases these servers might be blocked by one of the following:
Your country. Some countries block access to Apple's and Amazon's servers
By your Internet provider. Some Internet providers block or severely limit access to those services
By your VPN software or router (if you have enabled a VPN)
By other software that might filter content on your device
