Check-in screen shows offline or no attendee list

Not available yet (updated 2026-10-28). This article describes a planned capability that is not built. Today the check-in screen needs an internet connection: it does not keep a copy of the attendee list on the device, does not save check-ins to send later, and does not scan ticket QR codes. If the connection drops, selecting Check in shows “Couldn’t reach the server — check your connection and try again.” The check-in may not have been recorded — try again: the Check in buttons stay usable, so reconnect and select Check in on the person’s row again. If it was recorded, you’ll see “Already checked in at {time}”. See Check in attendees for what the screen does today.

The check-in screen is showing an offline warning or says there is no attendee list cached on the device.

What’s happening

Section titled “What’s happening”

There are two different states that look similar but have different impacts:

  1. Offline with cache — the device has lost connectivity but previously loaded the attendee list. You can continue checking in. A yellow banner shows headline “You’re offline” and body “Check-ins are queued and will sync when you reconnect.”

  2. Offline, no cache — the device has never loaded the check-in screen while connected. No attendee list is available. The screen reads: “No attendee list cached on this device — connect once to load it. Until then, record check-ins on paper and use manual search to reconcile when you’re back online.”

How to fix it

Section titled “How to fix it”

If you see the “You’re offline” banner:

  • Continue using the check-in screen normally. QR code scanning and name search both work against the cached list.
  • Check-ins are queued and sync automatically when connectivity returns.
  • If the yellow banner also warns that the list is stale (more than 24 hours old), the cached list may be missing recent registrations. If connectivity is available, reload the check-in screen to update it.

If you see “No attendee list cached on this device”:

  • Connect the device to Wi-Fi or mobile data.
  • Reload the check-in screen. The attendee list will download automatically.
  • While waiting, use a different device that has the cache, or record check-ins manually and reconcile later using the Attendees tab on the event detail page.

If that didn’t work

Section titled “If that didn’t work”
  • Cannot connect to Wi-Fi or mobile data — use a different device that is already connected and has the cache. You can also print the attendee list from the Attendees tab on a computer and use it for manual check-in.
  • Sync pending indicator remains after connecting — wait a moment for the queue to flush. If it does not clear within a few minutes, reload the check-in screen. Check-ins are not lost — they remain in the queue on the device until they sync.
