Through an OS service yes, but not a hosted backend service. Obviously that service has store the notification in plaintext (although everything on an iPhone is encrypted at rest, but notification crypto keys have to stay in active memory for the lock screen to work), otherwise it wouldn’t be able to display the notification text.

Apple support applications sending encrypted notifications, where the OS launches the app the decrypt the notification body locally and pass it back to the OS for display.

I think the idea here is that the notification text was also being put somewhere else that was not really tied to the lifetime of it being shown on screen.

This thread is about Apple servers accessing the contents. Of course the OS has access to the contents of your messages, how else do you expect it to show a preview of the message? Do you want each notification to be a custom-rendered widget from the app?

If the contents are that sensitive you must disable the preview. Even then, the OS has access to the pixels in your app so it really is a moot point.

The caching issue here was evidently a bug.

I don't think there is anything here that I disagree with?
