there used to be ability to define default notification sound in settings, so I could set the default sound for all texts that come through (I was still able to go into individual conversations and customize). this is now missing and I am forever stuck with a notification sound I don't like and it scares my dog. I can't just change it on a conversation level because any new texts from unknown contacts still come through with the old sound I defined before this setting disappeared. I also am unable to override this by defining a notification sound on the main settings on my phone. I feel very frustrated and wish it would just go back to the way it was. thank you.
