Hi, I have an issue syncing my Attack Shark X68 Pro with SignalRGB:

- Not detected via wired USB; only recognized via 2.4GHz wireless.

- On 2.4GHz, the RGB lighting is unstable and constantly flickers.

Any fix or plugin for this? Thanks!

Please submit a bug report while the keyboard is plugged in with the USB cable. You can do this through the bug icon found on the upper right panel of the app. We’ll need to look into logs and other information to see what’s going on.
