Notifications aren't working for Costco MasterCard users. Based on previous reviews this obviously wasn't tested well at all. The transition has been nothing but a hassle. The Capital One app for the Costco MasterCard always worked perfectly. This is one of the reasons I cancelled my previous CIBC card a few years ago. You cannot reach anyone online and the phone is always backed up for hours. There may as well be no customer service at all as a result.
