Rent movie on Apple TV, French audio only

I have exactly the same problem, Oppenheimer, Switzerland. French the only audio option. Just paid rental for a film I really wanted to see in original. Very disappointing. Do I really have to buy the DVD?

The default language settings may be different from original audio. If available with a title, then users may change the audio language tracks and subtitle track to any one of the other included tracks.

Note that available language tracks differ by title and by country or region, as set for each region by the supplying studio(s).

Change subtitles or languages for videos in the Apple TV app or iTunes Store - Apple Support

In some multi-language countries, there may be different editions of a movie title, each with their own language support, each as a different store item. If you accidentally ordered the unintended edition, then please contact the iTunes Store staff about undoing the purchase and getting the correct edition instead, if you still want it.

Please contact the iTunes Store staff for issues with select iTunes Store purchases. They should be able to check content files and check your account, to see what is preventing all the promised features of movie playback.
