Seems this is a free-for-all to drop language gripes, so here's mine about Apple TV.
Have a family member who only speaks Japanese. My Apple account is in Finland. We wanted to watch The Martian together, but can't select Japanese dub even though that audio track definitely exists. They just don't show you the options not relevant to your account country, and the only way around is to change your whole Apple account to a new country.
Which you cannot do while you have an active Apple TV subscription.
End result: unable to watch Apple TV as a family.
