This is definitely working as intended--the preferred audio language is a setting separately from changing the language within a play session. The latter is expected to be temporary, whereas the former is meant to change the setting across multiple explorations.

@cam-pinheiro did you find this confusing or perhaps unintuitive? There may well be a need here to improve the user experience.

@BenHenning Oh ok, I see it. It makes sense.
In the first moment it was a litlle confusing because I though if I changed in a play session the preferred should be change. But it is true, it is temporary. If I select portuguese audio and close the chapter, when I open again the audio return to default language (English).
