The "Update" section at the bottom of the iOS 11.2 MacRumors article touches upon that:I just updated to 11.2 but I don’t see Apple Pay cash anywhere. Yes I do have 2 factor authentication on.
When it rolled out to the beta, it was a gradual rollout and I didn’t get it until 6 hours after others. Possibly the case today is that they have activated it server side, but it’s slowly rolling out to users.Why do some people have Apple Pay Cash and they aren’t on the beta?? They have posted a screen shot showing they have it.
