Smart sorting doesn't work in 3.2.0 for iOS

Smart sorting has disappeared from the app. It used to work perfectly in the previous version, but it is no longer a thing with this new release. There is no sidebar cone as in the old version either, so I can't select "library mode" either. All I can do is have all my videos shown in the same root folder of the app, and then sort how they're listed (alphanumerical, duration, etc). There's no option to turn it on or off in the settings either using the bottom menu that's always visible now.

Version: 3.2.0 for iOS. My OS: 10.3.3 iPad 12.9" 2017 model.
