How to stop mirrorlink from activating

Have a 21 plate Superb L&K.

Not really sure what setting has been changed or what has happened, but for some reason mirrorlink always tries to activate if I plug the phone in.

This never used to happen, the car would connect wirelessly to the phone and use android auto, and then if plugged in it would continue to use android auto.

But for the last several months, I can connect wirelessly and it will use android auto, but if I plug in then it tries to use mirrorlink, which then does not connect. Unplugging the phone doesn't help and it just won't connect until I turn the engine off and on, or delete the phone connection and restart (and do not plug in the phone).

Effectively, I can't actually charge my phone in the car anymore. Driving me a bit bonkers, so I would really appreciate it if someone knows the fix to this!
