How do I remove an old device from sync?

Each device that uses iCloud Sync keeps its own copy of your data in your iCloud, and that copy stays after you stop using the device, even after a reinstall or a new phone. Remove it when you no longer use a device, for example one you sold, replaced, or reset. On a device that still syncs, open Settings → Device Sync → Devices and tap Remove beside the old device. Devices not synced in 90 or more days are marked. Removing deletes only that device’s copy from iCloud, including details it still held of contacts deleted elsewhere. This device keeps everything it has already synced, and your other devices aren’t changed. If the removed device is still in use, it adds its data back the next time it syncs; turn off iCloud Sync on it first if you want it to stop. Before removing a device, this device must finish syncing its data; if asked, go back, tap Sync now, and fix any problem the status shows. If the device uses a newer version of WitnessWork, update this device first. Devices replaced by Rebuild iCloud data can be removed at any time. Photos aren’t stored per device, so removing a device doesn’t remove photos; use Remove iCloud photos for that. Devices is part of Settings → Device Sync on every option, all Supporter features: with iCloud the copies are in your iCloud, with Google Drive on Android in your Google Drive, and with Cloud Sync, removing a device deletes its copy from WitnessWork's server. If you need help, use the Help Center’s private support option and keep householder details out of public reports.
