"You have to buy more phones."
Translation:Tienes que comprar más teléfonos.
This is very frustrating, even though I know it is still in testing. I had 'debe comprar mas telefonos', and I was corrected as follows:
You used the él/ella/usted form "debe" instead of the nosotros/nosotras form "debemos". debemos comprar más teléfonos which is 100% wrong.
