Problem with speed editor -

Hello, everything works on the laptop, but on the PC via USB it is displayed in the DaVinci Control Panel, but it does not work and there is no indicator on the keyboard. It also does not work via Bluetooth, although there is a connection and it shows the battery charge, but it is not displayed in the DaVinci Control Panel.

Yesterday, by some miracle, it worked, and only via Bluetooth, it didn't show up in the control panel. I couldn't repeat this miracle a second time.
