My case seems to have created a fault all by itself. The earbuds work fine. However the function button seems to do nothing. A light press does create a short white light and then nothing. A long press doesn’t start the pairing process and an even longer press doesn’t reset the buds (red light). Its as if the case doesn’t know the lid is open and therefore doesn’t activate the function button. Anybody else had this problem? When I put the buds away and close the lid they don’t cut off automatically. i can see they are still connected until I give a very quick click on the function button, then short white light and they disconnect.
