Pillow uses Apple's iCloud to store and synchronize your data between your devices. iCloud is a service provided by Apple and we do not have control over that service.

If Pillow stops synchronising your data please check the following troubleshooting steps:

Check the Apple System Status page in case iCloud is down

Sometimes Apple's services are unavailable for technical reasons.

Visit the following link: https://www.apple.com/support/systemstatus/
Make sure the status for all iCloud services is green
If the status is not green please wait until all issues are fixed and try again.

Make sure you have enabled iCloud synching in Pillow:

1. Open Pillow on your iPhone/iPad → Tap on the Settings icon on the top right corner 2. Scroll down and make sure "Sync with iCloud" is turned ON

Note: If you are trying to synchronise data between two or more devices, please make sure that your devices are setup with the same AppleID.

Make sure your device has enough storage space

iCloud synchronisation will not work if your device is low on storage space. Please make sure that your device has at least 5-6 GB of storage space and try again.

Make sure you have enabled iCloud for Pillow under the Settings app:

1. Open the Settings app on your iPhone or iPad (the one with two cogs)

2. Tap on your name at the top

3. Go to iCloud → Make sure the switch for Pillow is turned ON

Ensure that your device isn't low on battery.

If you have enabled iCloud for Pillow, please note that syncing may be disabled by iOS to reserve battery. Ensure that your device isn’t low on battery or in Power save mode.
