Determine the scope
Find out whether the problem affects one device, one network/geography, one app version, or most users. A widespread issue points to central infrastructure or a release problem.
Device checks
Record app version, user, device identifier, pending count, attachment size, last successful sync, storage, device time, and whether the same record repeatedly fails.
Server checks
Review sync API latency, Go sync service health when enabled, Redis/Horizon backlog, PostgreSQL CPU/locks, network errors, and request-size limits.
Protect local data
Do not uninstall the app, clear storage, or reset a device with pending unsynced records unless a controlled recovery has already copied or safely transferred those records.
