What should I do if I haven't given some permissions to unTill Air?

If you haven't granted unTill Air permission to access the camera, you won't be able to scan QR codes within the app. Similarly, without permission to search for devices nearby, you won't be able to print tickets from the printer.

The app requests permissions before linking the screen and when printing the first ticket.

If you previously refused to grant certain permissions and now wish to change this, navigate to your device's settings, find the 'apps' section, select 'unTill Air', and grant the necessary permissions to continue using the app.
