Things to look out for and try if your block won't pair:
- Make sure your blocks are fully charged.
- Make sure your Bluetooth is turned on as the blocks pair to your device via Bluetooth.
- Try re-opening and closing your app.
- Try resetting your blocks by holding the power button down for ten seconds until a white light flashes.
- Try turning your Bluetooth off and on.
- Try shutting down your computer/device and restarting it.
