Please check if your firmware is the latest in Fnatic OP. You can find this under the 'Device Info' section in the Fnatic OP software. 

We can recommend you to update the Windows and update your drivers in order to see if that will resolve the issue. 

If the issue is still not resolved, try to re-install your OP software, download it again from here https://fnatic.com/gear/op and perform a keyboard reset.

With the keyboard plugged in:

1. Please locate the reset hole on the underside of the keyboard (below the keyboard feet)

2. Please use a pin and hold in the hole for 10+ seconds.

3. Observe the keyboard RGB flashing, and wait for the reset to complete.

If this does not fix the problem, please contact us on [email protected] along with the video recording of the problem, your order ID and serial number for the keyboard.
