The iPhone won’t let update games or download anything it says “verification required please update your billing info “.Even if you update your billing information it will still say payment has been declined. Every time a message pops up saying to “press continue and sign in to view billing information”.
Many users to try switching their payment cards but still no help and the message keep on coming up. This does not seems to be issue with card entered in the appstore. But some issue with Apple software. For some user while adding new card it keeps bringing back to “checking my billing address”. The users are not able to update the card info nor remove it.
