When Apple launches iOS 11 on Tuesday, the software will be without one of its most anticipated features.

In a post detailing the release of its new mobile software, Apple highlights Apple Pay Cash, a feature that allows users to easily send money to friends and family through Messages. Unfortunately, the peer-to-peer payment service has been hit by a delay to sometime this fall.

As MacRumors notes, Apple recently indicated Apple Pay Cash would be delayed until a future update, and today’s post makes it official. Of course, the company made no mention of the delay at its recent iPhone event. It’s unclear how long the feature will be in the cooker before it’s ready for an official release.

Coming this fall with an update to iOS 11 and watchOS 4, apple Pay users will be able to send and receive money from friends and family quickly, easily and securely. Pay and get paid right from Messages, or tell Siri to pay someone, using the credit and debit cards they have in Wallet. When users get paid, they receive the money in their new Apple Pay Cash card in Apple Wallet and can use the money instantly.

Apple Pay Cash is very similar in execution to something like Square Cash, a peer-to-peer payment service that’s available for both Android and iOS. The charm of Apple’s service is that it’s built right into the operating system (with plenty of setup on the user side).

Apple is typically pretty quick to release updates once a new software hits, so hopefully the arrival of Apple Pay Cash isn’t too far off.

Apple users will be able to download iOS 11 starting Tuesday.
