Help: airgapped signing issues

Main article: Offline transaction signing

The QR Code is too bright/dark and can’t be scanned

• If your webcam supports it, enable “Manual exposure” and adjust the slider so the QR code is clearly visible
• Resize the window to increase the size of the QR code
• Adjust the brightness of your monitor
• Enable dark mode (Settings -> Appearance -> Theme)
• Hold the webcam closer or farther away from the monitor
• Move to a brighter environment, turn on overhead lighting
• Click the settings icon next to the QR code and decrease the fragment length and decrease the speed (by increasing the ms / fragment)
• Try with a different webcam

The progress bar is stuck on 99%

Keep scanning until it hits 100%. It might take a few seconds if the scanner missed a fragment.
