Server Version#: 4.22.2
When I have a Collection that lacks its own Content Rating…
…then it correctly includes “None” in the Content Ratings filter list.
However, when I actually select “None”, the Collection is not shown.
So there is no way to find collections that lack a content rating, because the filter’s list and the filter’s results are inconsistent with one another.
This would not be a big problem except for the fact that Collections that lack content ratings are not shown to restricted users even if the underlying movies are allowed (for which I’ve submitted a Feature Suggestion). I had to individually select each Collections and look at its Content Rating, manually editing some of them before my kids could see these movies.
