I'm not quite sure if it's because of Android 12 or Google Pixel 6, but after I switched from OnePlus 6T (Android 11) to Google Pixel 6 (Android 12), the auto-connect doesn't work. The service detects headunit by connection to Bluetooth, but somehow it have issues to connect to head unit WiFi (it's visible and connectable). Sometimes it takes a few seconds / minutes until phone automatically connects into it, but I anyway need to press "force connect" on notification to launch it.
