I have one personal iPhone and one for work. The work phone downloaded and installed iOS 16.5.1 (a), but the other phone says it’s up to date with just 16.5.1, even though earlier I saw a notice to update that phone too. I.e. that notice disappeared. Why the disparity??
iPhone 12
Simply apply the new update when it is available again.
So what happens if you've already downloaded it - there's no way to roll it back? It doesn't seem to have broken anything on my iPhone or iPad (so far) and I don't use Facebook or Instagram, but may need to use Zoom (three apps reported to have problems)...
Edit: OK, further reading suggests it's just an issue accessing the sites with Safari, so my Zoom app shouldn't be affected. Also, found out I can remove the update if needed (but, since the alternative returns a potential vulnerability, I'll hold on that).
So far, it looks like Apple messed up. Check back in a day or two and things will likely be straightened out.
Yes, that it does.
The Rapid Security Response was published though: About the security content of Rapid Security Responses for iOS 16.5.1 and iPadOS 16.5.1 - Apple Support.
iOS 16.5.1 (a) notice appeared and then disappeared.
