On Monday 31 August, exhibitors and organizers scanning badges began seeing an error after a scan, with the scan then stored as an offline scan on the device. This happened on devices with a working internet connection, which is why it was initially mistaken for a venue network problem. On iOS, some devices showed only a red banner that did not open when tapped.

No lead data was lost. Two mechanisms protected the data at the same time. Server side, each lead was saved to our primary database at the moment of the scan, before the step that failed, so the lead already existed even when the app reported an error. Device side, the app's offline mode captured the scan and synced it once scanning recovered. Because a repeat submission of the same scan updates the existing lead rather than adding a new one, this did not create duplicate leads.

The cause was specific to the badge scanning path. Registration, event pages, meetings, messaging, exports and the organizer back-office were not affected during this window.
