# April 2023 - Build 1.0.29

## Bug Fixes

- Mobile Check-in app users can now check in an Attendee to a specific Session using a QR Code.
- Previously, an error would occur when using the Blackthorn External ID/Digital ID process for Events with no Attendee records. This issue has been resolved.

## Enhancement

- A new global setting has been added to the Mobile Check-In app. The new setting controls the behavior of the Badge Printing pop-up after a QR code is scanned and is disabled by default. To enable the setting, go to Settings and set QR-Scan Badge Print Popup to “Enable.”
