When to resend
If a notification fails delivery (red cross in the status column), it is usually because the customer's device token is stale or LINE responded with a transient error. The system already retries failed sends up to three times over a 40-minute window automatically. After that, you can re-send manually from the history page.
How to resend
- Go to Admin → Settings → Notification History.
- Find the row of the failed notification using filters or search.
- Click the … menu in the last column of that row.
- The popover shows the original title and body. Click Resend.
- The row's status updates to Pending while the resend is queued. It then becomes Sent or Error depending on the result.
Per-row only
Resend is per-row only — there is no bulk resend action. For a large failure batch, fix the underlying cause (have customers reinstall the app to refresh their token, top up LINE credit, etc.) before re-sending so the retry has a chance to succeed.
