iOS app 'screenshots' (in task selection mode) are often dated, even after multiple openings of the app. I get that they are meant to be just that, snapshots, but if those aren't up to date, you may as well just show the app icon.

Up to once a week, now, iCloud (in OS X settings) asks me to verify my password when "nothing has changed" (no purchases, etc). It then spins for a long time and there's no acknowledgement that it 'succeeded'.

Several more.
