Offline and sync
Sonaa works without a connection and catches up when you're back online.
Everything you do is saved on your device first, so Sonaa Week keeps working offline. Changes are sent to the server in the background and reach your other devices from there.
Checking the status
Settings › Sync shows whether everything has reached the server, when it last synced and how many changes are still waiting. Sync now starts a sync right away.
When something can't be saved
Rarely, the server refuses a change. It then stays on the device that made it and is listed under Could not be saved. Retry sends it again; if that doesn't help, it's safe to leave it there while you get in touch.
Signing out
Signing out removes your data from that device. Make sure Settings › Sync says everything is saved before you sign out on a device that was offline.
