I can't seem to connect to the ear buds through the Bose connect app. When trying to connect the buds are charged and the lights also light up for sometime and switch off. App would afterwards say can't connect. Tried several times with no luck. Through the BT pairing the earbuds connect however the volume is very low even after increasing the phone volume. Something seems to be wrong, connecting via One Plus 9 Pro with the latest OS12 version.
