Workaround: Ensure your device is connected to your Wi-Fi network.

The device that initiates the pairing needs to use the same iCloud account as the home hub. Only the owner of a home, not an invited user, can pair Matter accessories. (76012945)

Memory Allocation

Known Issues

The system memory allocator free operation zeroes out all deallocated blocks in iOS 16.1 beta or later. Invalid accesses to free memory might result in new crashes or corruption, including:
- Read-after-free bugs that previously observed the old contents of a block may now observe zeroes instead
- Write-after-free bugs may now cause subsequent calls to calloc to return non-zero memory
To debug these issues, use Address Sanitizer and Guard Malloc (see libgmalloc(3)). (97449075)

StoreKit

Resolved Issues

Fixed an issue where restoring transactions wouldn’t prompt for authentication or restore any transactions if there was no App Store account signed in. (99506258)

Fixed an issue where purchasing or restoring in-app transactions with hosted content would block new purchases or restores from processing. (100117681)
