We are aware of the following bug(s) that are ongoing or were introduced with the arrival of Hotfix Patch 0.21.6:

[Update July 5]

• We are aware of a bug with the music sheets such as, notes continuing after the sheet has ended and some instruments not matching harmony or key. Until the fix can be implemented in a future update, to end the ongoing music, please change your location to a different level/map.
• For some, the inbox message at the start of the Days of Music event was not in their device's set language. This has been fixed, and restarting Sky should show the message in the correct language.

Thank you for your patience while we worked to resolve these issues.

-----------------

• In rare cases, spamming notes on the violin may cause the game to lose sound.

We appreciate your patience and apologize for any inconvenience these may cause while we work to resolve them in a future update.
