Carsifi doesn't disconnect; call menu issues when connected

Car model(year): Hyundai Palisade 2022
Phone model(Android version): Samsung Note 20 5G (not the “Utlra”)
**Carsifi adapater firmware version:**18.0

Issue description: Firstly, Android Auto keeps connecting even after the car ignition is off. SOmetimes Calls are not visible on my phone.
Secondly, When the car ignition is on and I make a call to an office with an IVR menu saying choose 1 for… choose 2 for this. Even if I press 1 or 2, the call does not detect it. It seems that I am just typing numbers on a different app.
