Scanning a QR Code

[GavinBlake]

Hi,
I’m new to AppSheet, but have done a fair bit of research around QR scanning.
I understand that in the emulator “The scan button is displayed, but will not scan anything and will always produce the same value: 111122333.”
However I’m not seeing the scan button at all.
I’d like a new customer to our business scan in, and then we store the URL and their basic customer info into the google spreadsheet.
I have the column as “scannable”.

Suggestions welcome!
