Apple has released minor 15.2.1 updates for the iPhone and iPad (iOS 15.2.1 and iPadOS 15.2.1, respectively). The update comes one month after the release of iOS 15.2 and iPadOS 15.2, which included a number of improvements.
The iOS 15.2.1 and iPadOS 15.2.1 update is a free download and is available on all eligible devices over the air in the Settings app. The new software can be downloaded on eligible devices over-the-air by going to “Settings” -> “General” -> “Software Update.”
Apple’s release notes for the update say it addresses an issue causing Messages sent through an iCloud Link not to load and it fixes a bug with third-party CarPlay apps not responding to input.
