Syncing across your devices

Everything you add to the church database — songs, sets, the rota — syncs to every member's device. Changes save on your device instantly, then upload in the background; when another device next opens (or comes back to the foreground) it pulls the latest.

Importing a big library. A large import (say a whole OpenSong backup) is dozens of uploads, one after another. The toast shows a live countdown — "Imported 84 — uploading 61 to the server…" — and finishes with "all synced ✓". That tick means the database has them all and every device will get them.

A few reassurances:

• You can keep working while it uploads. If you refresh or close the tab mid-way, the songs are saved on your device and finish uploading when you reopen — nothing is lost. The browser will also warn you before you leave if an upload is still going.
• Do the import once, on one device, into the Church database (the dialog asks). Let it reach "all synced ✓" before checking another device.

If something didn't sync. Open Settings → Library. If any writes are still waiting, you'll see a line there — and if one was rejected, it names the reason. The Re-sync library to server button re-pushes your whole local library; it upserts by ID, so it's always safe to run and never makes duplicates.

Same church on every device. Sync is per-church, so make sure each device is signed into the same church account — songs added to one church never appear in another.
