There are 2 sound bugs.
- After watching the ad bears, there is a repeating sfx sound that doesn't stop until you close the app. Muting the sfx from settings doesn't stop it.
It's not an echo but a repeated sfx sound that didn't stop even after 5 minutes.
- There are instances of no sound at all until there's a splash sfx from fishing. Then sound works again.
Update: #1 doesn't happen anymore (for now at least) but #2 does
