Parking assist unavailable

Hey all I had a parking assist unavailable warning come up, wet and miserable weather made me think it was rain and dirt blocking sensors. Car cleaned and a lovely day today and still had this issue and if it doesn’t come up miles from the car in front I’m getting alerts to stop! Gone into service menu and all sensors are green. Have restarted and problem persists. I’ve requested a service in the app but in 48 hours I’ve had zero response to the request at all… Anyone got any other suggestions I could try? Thanks!
