This issue still persists for me. Occasionally on the simulator (and even a physical test device), the .inline or .timer styles will count every second, but usually it freezes the second count and doesn't refresh until you change screens and change back. Seems to revert to updating the text every minute or so. Disappointing... at the very least, there should be an option to configure what fields are displayed in the text style (i.e. don't show seconds, especially if we can't expect them to be in real-time).
