Bluetooth streaming to car not connecting - correctly

Bit of a bizarre one, I think. Got a new Peugeot 3008, when I first connected my P20 Pro to the car, it worked for both telephone audio and streaming. The next time, when I start the car, it makes a telephone bluetooth connection, but the streaming option does not connect

When I select the streaming option to connect from the car menu, I get the following error

On the phone, the media audio slider stays off

However, if I go on the phone, and slider the media audio, it instantly connects to the car

Any ideas

Yes - media audio has to be on for streaming. (It should stay on once you turn it on. But it may take a time or two before it"sticks". If it keeps turning off, contact Huawei.

It's not that it turns off, the slider never switches on when the car tries to make a media audio streaming connection and gets that error ... To enable the streaming I have to manually enable the media audio slider, but don't have to with the phone audio
