Apple Pay Cash Not Released Yet!
Although iOS 11.2 is already live and we’ve informed you that Apple Pay Cash will be finally released along with this 2nd major iOS 11 iteration, Apple’s person-to-person payment option isn’t available yet because the system isn’t ready. Apple planned to release iOS 11.2 on Tuesday, December 4 but has been forced to roll it out a couple of days earlier in order to patch the nasty December 2 date bug. Apparently Apple Pay Cash still wasn’t ready for a rushed release and we will most likely see it go live by December 5. In fact, Apple Support has confirmed on Twitter that Apple Pay Cash will become available
"early next week".
