If you saw weirdness with any of those — including in-app or web payments for Apple Pay or transaction notifications in Cash — between 6:15AM ET / 5:15AM CT and 6:49AM ET / 6:49AM CT today, Apple says it’s resolved the issues. As MacRumors notes, Apple didn’t say how many are affected.
While Apple’s status page still showed an active outage, I sent my partner a dollar (before reading that the Apple Cash issue is related to transaction notifications). When asked if she received it, she said, “Yes, great test.” Indeed.
Update December 20th, 9:56AM PT: Updated to reflect the outage was resolved.
