iTunes 12.5.4 shuffle issue
Updated to iTunes 12.5.4 for a large classical library (more than 41,000 individual tracks and nearly 5,000 groupings). I prefer to listen to multi-movement classical works in whole by work, usually not by album. Immediately following update, "shuffle by grouping" fails to recognize all but a tiny few designated groupings. Those it does recognize seem to be by virtue of being included in the last playlist I accessed before update. Using "get info" to reenter groupings doesn't seem to help. Is there a fix?
