Thanks everyone for the follow ups. The info is very helpful.
The team has been debugging this issue with lag across several browsers since it was reported; with this most recent version release, the team is only able to detect the issue continuing in some cases in Chrome, and not in Firefox, so please check across different browsers if you can. They're continuing to actively work on finding out the root cause.
As part of the optimizations on Chrome, the team has made a change that attempts to free some space on first load of the game, so in your case IImaestroII, your sound settings should be saved following the second load of the game.
Regarding the mobile version for Android, the team is also aware and investigating the cause of these performance issues that some are experiencing. I hope for more news as well on this.
This is of course not the experience we aim for and we're sorry this is still occurring. :/ We will provide more updates about all of these issues as soon as we have them.
Thanks once again Managers.
