Hello, last 3 update (dec, jan, febr) could not fix the issue, you can go back to 01.nov.2019 firmware, it is the last working firmware.

I have found a workaround to fix this temporarely , till Samsung releases a patch for fixing it.

Well , when Mobile phone is trying to connect to the car bluetooth device , that time do a call using the mobile phone.

When call established and you are talking to the one you have called , after 10 sec the connection will be established with the car audio system and then it will stay connected. But , as been said, the connection is valid  till the next time you will switch off the car and break the connection. So every time I get into the car , I do a fake phone call to a number and wait till the connection is established.  Try it

I think it relates to the smart lock of the screen, it seems that if the screen is active, Bluetooth connectivity is fine.
