Anyone else run a Logitech Crayon that suddenly is not producing any lines on an iPad? After trying turning it back on and off, reinstalling the driver, and even rebooting the iPad, I suddenly discovered the real problem. Sometimes when I’m placing the Crayon in its holder on my STM case or when I’m fidgeting with it I must have loosened the tip. The tip can be too loose for the Crayon to work even though it is still attached and looks the change.
So if your Crayon suddenly stops working, but it shows power when you tap the button, try twisting it counterclockwise to tighten. It may just start working again.
