Apple has released iOS 15.2.1 Last week, Apple has closed its doors for iOS 15.2 downgrading on iPhone, iPod touch, and iPad, meaning users who have upgraded to iOS 15.2.1 won’t be able to go back. iOS 15.2 can work once more, but if anyone is using iOS 15.2, they can continue to use it.
iOS 15.2.1 is released to fix a bug where messages may not load photos sent using iCloud links, and third-party CarPlay apps may not respond to data input on iPhones.
