If you’re having trouble with your Tiller, there’s a few things we suggest.
Firstly, unplug it and plug it back in again. You’d be amazed how often this helps!
If that doesn’t work, we'd recommend checking if you're connecting via a USB dongle or monitor. Sometimes use of these accessories can impede proper operation of Tiller. If possible, plug Tiller directly into your computer.
Next, try restarting the app.
And finally, try restarting your computer.
