Hello, just go to the settings of your game and check if the music and sound have not been closed mistakenly. You'l find what you're looking for there.
My vibration (haptic feedback) also stopped working. The option to turn it off/on is not showing anymore either. The game is no fun without the haptic feedback. Uninstalled and reinstalled did not fix nor did restarting phone and game. Please help!
Hahaha I'm very happy for you. As you have seen, sometimes they are only temporary incidents, that's why we always ask to log out, restart the device and log in again, to solve these small problems.
