We have cardholders across the US, in all time zones. They have mentioned that their phones/email notifications are coming to them during nonworking hours, and in some cases, very late/very early. It would be great if they could set the hours that they wish their notifications to be sent between. Or at the very least, to be able to put their time zone into their preferences so that the notifications are only sent 9-5 M-F based on their time zone.
