@LuShuai We had the same issue, after we updated our test device to iOS 16.0.2 our app stopped reading 2D barcodes properly (both QR Code and Data Matrix). On iOS 15, there was no issue detecting FNC1 character within the encoded data, which is used to read different GS1 elements. After the update, the app was unable to correctly detect the FNC1 character as well as other issues, which caused the workflow to be broken. Today, we installed iOS 16.1 beta 3, I confirm that the app is working properly as intended, and the scanner is able to detect FNC1 character successfully. Everything went back to normal.
