I just discovered recently through another user with a similar issue, the results are based on the language you set for preferred audio language under your account settings. Do you have a language selected there? Leaving that on “Select language” will cause this issue. Pick your appropriate language.
Since you have the “prefer audio language” set to none, it’s not finding any matching trailer.
The thing is, is that there is no “Select language” option. The obly options are specific languages, unknown, and none. Am I in the right section of settings?
Edit: Silly me. Let me try a lamguage, I confused myself lol.
That worked. I cannot believe such a simple setting change worked. I had “None” originally set to let movies play in their native language always haha. Wooooooooow. Almost 3 years for a simple toggle.
