Yess same, I downloaded it to play in June but after playing my ass off to have more than 1200 diamonds and spending them, I still couldn't get one single R (or higher) card from my bias so I decided to use other cards to trade for one but after trading it gave me the card from my least favourite theme so I deleted the game right away, now I regret 😭
if you go to setting and then sync, you can adjust both speaker and bluetooth sync! (it’ll take a minute or less since it’ll guide you on syncing the music)
