Apple has recently updated the IOS 15 function page, indicating that AirPods Pro and AirPods Max has been postponed to "this fall later", which means that the initial version of iOS 15 will not provide this feature.
Apple does not provide postponation, but several other features of iOS 15 can be launched later this year, such as SharePlay, add driver's license or state ID to wallet applications. Last month, Apple also marked the iCloud Private Relay as a beta function.
If you lose AirPods Pro or AirPods Max, while others have iPhone, iPad, or Mac, look up the network will be able to transfer the rough location of the headphones directly to you. This feature is intended to help you enter the Bluetooth coverage of AirPods so you can play the sound and find them.
After more than three months of beta test, IOS 15 will be officially released tomorrow. This software update is compatible with the same iPhone as iOS 14, including older devices such as the initial iPhone SE and iPhone 6s. iPadOS 15, Watchos 8 and TVOS 15 will also be released tomorrow, while Macos Monterey has not yet been announced.
