My devices are not syncing. What can I check?

First check Settings → Device Sync: devices sync only with your devices that use the same option (Cloud Sync, iCloud, or Google Drive), so choose the same one on each. With Cloud Sync, keep the app open on both devices and check your internet connection; Sync now retries at once. If it says Cloud Sync is paused, nothing is wrong on your side: changes wait on this device and sync when it's back. For iCloud: on iOS, use the same Apple Account, turn on iCloud Drive, and enable WitnessWork under iCloud on each device. On Android, see “Google Drive Sync isn’t working on my Android device. What can I check?” iCloud sync requires Supporter access. Open Settings → Device Sync and use Sync now. Changes waiting to be sent are retried; an unreadable file or newer app version is shown in the status, so update every device and try again. The status shows Uploading to iCloud until Apple confirms the upload, and Last synced counts only confirmed uploads. If your iCloud storage is full, changes stay on this device; free up space or upgrade your storage in Settings → [Your Name] → iCloud and uploading resumes on its own. Keep an exported backup and the device containing your latest data. Rebuild iCloud data replaces the iCloud data with this device’s data and removes iCloud photos it doesn’t use. Your other devices switch to that data the next time they sync, replacing changes made on them before then, and the Home bell notes it. Update WitnessWork on every device first: an older version keeps its own data until it is updated. Contact private support from the Help Center if syncing remains incomplete. Keep householder details out of public reports.
