Why isn't the alignment stick being recognised?

Refer to the user manual and place the alignment stick in front of the Square Golf device. Ensure that the colour of the floor mat is distinct from the alignment stick and that there are no bright-coloured objects, like golf balls, around the alignment stick. It may take up to 10 seconds for the alignment stick to appear on the app screen. To complete target alignment, press the OK or CANCEL button in the alignment stick settings window on the app, then remove the stick. Proper setup and patience will ensure the alignment stick is recognised accurately.
