So, you will not be able to search or sort by comments in SmartPlaylist, since all comments are now "missing" on the device.
I have reported this bug to Apple. (This now makes 10 open bugs I have reported to Apple. Instead of fixing them, they add more bugs ...)
Here's my balance:
Used to work with iOS 4.1, but no longer work with 4.2.1:
- DiscNumber, DiscCount
- Comments
- BeatsPerMinute
Never worked:
- UserGrouping
Doesn't work properly:
- ReleaseDate (does not seem to work for dates before 2000)
- Lyrics (works only if the lyrics were displayed in iPod music app before)
- LastPlayedDate (wrong time zone when set on device, is shifted when syncing)
