After downloading today’s update I noticed some sound effects weren’t taking place, most notably Medusa’s passive. I may be the only player on these forums who play this game with sound and I kind of miss the noise she made. 
You’re not the only one:

(and despite that thread’s title, the problem seems to affect Android too)
Huh, this game has sound? 
My wife hates that I play this game as is, I imagine she would divorce me if I had the sound on…
