## Troubleshooting

| Problem | Solution |
| --- | --- |
| Can’t find an Attendee | Double-check spelling; Try searching by email; Connect to Wi-Fi and tap **CHECK SF FOR NEW ATTENDEES**; Add manually if still not found |
| Search returns no results | Must use the Attendee's full **First Name**, full **Last Name**, full **Email**, or company (**Account**)—no partial matches. Must have loaded the Event with Wi-Fi connectivity before going offline. |
| Check-ins say “Pending” | Not yet synced; connect to the internet, tap the **Cloud** icon, then tap the **SYNC X CHANGES** button. |
| Sync fails / error shown | Tap **Retry** in the Sync Manager; copy the **Request Id** and contact [Blackthorn Support](https://community.blackthorn.io/s/support) if it persists. |
| The QR code isn’t working | If there is low light, try turning on your phone flashlight by clicking the lightning icon when your scanner is open. If that fails, try searching by name or email instead. |
| The device is slow or unresponsive | Connect to the Wi-Fi to download the Event before going offline. If thousands of Events are active, try unpublishing past Events. |
| Accidentally closed the app during sync | Don’t worry—sync will continue when you reopen the app. |
| Still need help? | Copy the **Request Id** from Sync Manager and contact the event supervisor or [Blackthorn Support](https://community.blackthorn.io/s/support). |
