My Twitter Photo Card got approved recently, and the domain has been whitelisted. However, due to issues with the image sizing, the Card type is being switched to the new Large Summary Image Card. All the appropriate tags have been modified/added; however, the card doesn’t work in Twitter at all.
I assumed that it would work, since our domain is already whitelisted. Is this a wrong assumption? Or is there a process for whitelisted domains to change their card type without going through the approval process all over again?
