Bluetooth connection custom automation problem

Hi everyone,

I got an iPhone 13 pro and I would create automation to open Spotify when Bluetooth connects to the car audio system (note: I have not Carplay, just audio BlueTooth).

First of all, I removed Apple Music App because there's no way to shut it down when Bluetooth connects to any audio equipment.

So, I go to Shortcuts APP, Automation tab, New automation.

Then I set -> When iPhone connects to <my car's bluetooth>

Do -> Open Spotify

then I add another Do entry: play music on this iPhone.

Ok, pretty easy, isn't it? But it doesn't work. If I press the play button to test the automation, it works perfectly. But If I connect the true Bluetooth I can only see the Automation notify but nothing happens. I need to tap in the notify and play manually the automation. This doesn't make sense.

What am I doing wrong?

Can you help me?

Nothing changes if I leave the phone unlocked during Bluetooth connection or even blocked in standby.

Sorry for my incorrect translation, I'm Italian and I don't know the commands' translation in the English version.

Thanks for the support.
