Sometimes while I’m playing, I’ve found that a certain sound effect doesn’t end when it’s supposed to, instead continuing on after the battle, into the city and into further battles, only stopping when I close the app and reopen it (even switching to another app only stops the sound effect until I go back to Disney heroes). I believe it’s the sound effect when a character is regenerating health, like when Ralph falls below a certain amount of health and regains it. Occasionally the out-of-battle city music will also do this, leading to it playing alongside the battle music and even a second playing of the city music. I don’t know if I’m explaining this very well but basically there are sounds that don’t end when they’re supposed to and keep playing until the app is closed
Worth noting, I play Disney Heroes on two different phones with separate accounts, one older than the other, and I’ve only encountered these issues on the older one, so it might have to do with the comparability for older devices or something. I believe my account on that phone is on server 6, if that helps
