Accepting call on car bluetooth then phone puts itself on loud

[katiekw]

Whilst driving, if I accept a call through my cars bluetooth after the call my phone will be on loud. It's incredibly annoying when notications are then interrupting my music 

- I'm using a Z flip 5 but it was happening on my previous phone S20 

- I have a routine set up that when my phone connects to my cars bluetooth it puts my phone volume up and opens spotify

- I have a watch 5 connected as well (I had this before the issue started)

- I've set up a routine that when my phone disconnects from my car bluetooth it puts itself on vibrate but this doesn't solve the issue 

Any help would be appreciated

Resolved the issue. Commenting on this in case someone else had the same issue.

Bluetooth > advance settings > turn off ring tone sync
