You have to enter a valid address, either your residential address or postal address if it is different. An address that is
recognised
on webforms.
Have you had this problem purchasing from other websites?
You need to get a green tick in each box (address/suburb/postcode).
The box that doesn't have a green tick has an invalid entry.
Me and another friend have had this issue occur yesterday as well.
All the checkmarks are there, I've triple checked for any issues on my inputs. Whether I type in my full address, or a single letter the box is accepting it as valid, then denies its validity when I press continue. I've also tried it on a different browser and on mobile, with no luck.
I'm also having the same issue. Whether I use an old card or add a new one, both say invalid. Trying to add a new card doesn't even give the option to input the card numbers, just asks for billing address, and even when entered correctly, it says invalid.
