My indoor trainer/Zwift setup is shared by two people. Right now, the Zwift app settings (such as volume levels) are applied globally regardless of who is signed in. These settings should really be associated with the user account.
Maybe I have the game volume turned way down because I like to listen to music, but when my partner logs in she wants to hear all the game sound effects in full glory. We shouldn’t have to keep resetting them to our preferred levels every time we ride.
