I also have bought several movies because it said it had latin American Spanish audio and they did not.
Where did you see that it had that audio exactly? Were you signed in with the same Apple ID as with which you made the purchase? It is not the same worldwide. It is not the same per reseller. Searching on the web might give results for other countries and regions as well, with other audio tracks.
What is the country or country-like region to which your Apple ID is set? Did that change recently?
It happens alot. And after I make purchase and realize I've been lied to,I back out of movie to find it doesn't say latin American audio anymore
How odd. It is an automated system, showing meta data as read from the supplied content. It shouldn’t be able to have audio tracks go missing suddenly.
Can you give a few examples of movie titles for which this happened?
