When an iOS update is available, VoiceOver does not read the download size on Settings > General > Software Update

To reproduce this behaviour there will need to be an iOS update available for your device.

1. Ensure that VoiceOver is enabled.
2. Navigate to Settings > General > Software Update
3. Perform a 4 finger single tap on the top half of the screen so as to place VoiceOver focus on to the first UI element on this screen.
4. Flick right with 1 finger repeatedly to move VoiceOver focus through all page elements.

You should find that VoiceOver focus ‘skips’ the element which states the size of the download.

It is also impossible to locate this element by touch.
