I recently traded in my iPhone for the new 15 Pro. The trade in credits are applied to my bill over 36 months (making my phone free) but it says it can take 1-2 billing cycles for the promo credits to appear on my bill. My question is, for my next 1-2 bills that will not have the promo credits applied yet, I assume I will have to pay the device payment. Will I ever get that portion credited back to me? Or does anyone know how that works?
