I lost my card I have been using for all my Xbox One payments. I have entered the new card (same company different number & exp date) However, two issues are now apparent after entering the new card. Frist, I can no longer split my payments (using store credit and the remaining balance on the card). I had been able to do this with the previous card but it no longer works. I have even entered another credit card and it too will not split (and I have used that card on other services to split payment). Secondly, I wish to delete the old card but either using the Xbox One option or the web account manager I am not able to delete the old card. I understand it may be an issue that it is my primary card (associated with the account) but, I do not see a way to change the primary account card to the new card. Any help is appreciated?
