All good, but if you have booked the package, I would suggest: either call the Concierge Service in your car (in the middle at the top where the SOS button is, it’s free) and ask them about it, or if that doesn’t help, make an appointment with your dealer and have them show you.
At least the internet radio should work for you then....
I haven’t booked the package myself; I share my phone as a hotspot, so the car connects to the internet that way and I can use internet radio. The other passengers can connect to the car via Wi-Fi and also have internet access. (But I also have a large data allowance

)
Seriously: it will 100% work for you too. If it works via cable for you, then it’s really just a setting on your phone that’s preventing the wireless connection from staying active....
Here’s something another user with Samsung and Cupra wrote:
Thank you for your comments. I took drastic measures and reset my Samsung. Although I constantly had connection problems and thought it was more likely a cable or physical connection issue, I’m happy to say that
so far everything is working perfectly! The really strange thing is that Android Auto now looks completely different. Although I uninstalled and “updated” AA according to the Play Store, it’s clearly a different version. I’m very happy with this situation as I feared having to visit the not particularly helpful service centre.
