I'm actually surprised none of the blogs / clickbait sites have picked it up... But I suspect even if Amex decides to update the hours in their app the vast majority of cardholders will go to the Sky Club or the Centurion by default (both of which are closer to all the B gates anyway). And having passed through the Centurion many times already since it opened it's never once been crowded / overflowing, so I don't even know if demand is anywhere back to pre-Covid levels / if it will be a problem any time soon
