My Acton 2 Bluetooth speaker is plugged in and is in discovery mode, however when it is added and paired to my Windows 11 PC, "Battery is 0%" is displayed and audio cannot be played, We've already updated the BIOS and downloaded the latest Bluetooth device drivers for Windows 11 but connection still fails.
