AirPods Pro 3 touch controls not working

Airpods pro 3 touch controls not working. Volume up/down will not alter the volume. On occasion when attempting to change volume the iPhone volume slider appears briefly but the volume never changes. On incoming calls squeezing to answer does nothing and I must answer using voice control. I've had them a week now, they are perfectly clean and I have tried all the suggestions found via online searches. Are they defective?
