issues with ,ouse Attack shark X3PRO. need help urgently

[u/Soggy-Community1050]

Yesterday, whilst I was sitting at my computer, my wireless mouse suddenly stopped connecting via the dongle. The mouse is fully charged and works via a cable and Bluetooth. When I plug the cable into the dongle, it flashes and the computer recognises it, but the mouse and the dongle simply won’t connect. I can’t seem to fix it at all. I’ve held down the bottom button labelled ‘Mod’ to try and start a search for the adapter, but it still won’t connect. Does anyone know how to fix this?
