Que yo recuerde antes se podía comprar en la pc pero ahora volví ya no me deja, no se si actualizaron el juego pero me gustaria saber si es un error solo mío o lo tiene la mayoría ya así

 

Hello, Thank you for reaching out to us.

I'm not 100% sure on what is your problem, would you mind explaining it a bit more in depth?
Is it about a Coin Shop? If it's a problem with the Coin Shop, you should click on orange button that says "Get Coins" and from there select the amount of Coins you would like to purchase. Fill out your information and the Coins should appear on your account pretty soon after.

 

Looking forward to your response.
