It’s dubbed in French and I can’t change it to English, which is the original language.
What is the country or region for your Apple ID account?
In Canada, the original language version and the dubbed version are two different items in the Store. Once purchased, you can’t change the language without buying the other item.
In France, only the dubbed version is available.
In Switzerland, there is a French dub and a German dub available, no English in either one.
non of my settings on my iPhone or account or anywhere are set in French. So why is this?
Your settings only matter when multiple language streams are available in the video.
Which languages are included, is determined by the supplying studio, Focus Features (Universal Pictures) in this case.
Can I get a refund for this?
