The Tibetan language (code bo) has different names in the language selector in the web and the app. I don't know Tibetan. This was shown to me by a friend who learned some Tibetan in the university, but he's not an expert.
On desktop and mobile web it's "བོད་ཡིག", which (probably) comes from core Names.php. This is also the name in the iOS app. This means something like "written Tibetan language".
On the Android app it's "བོད་སྐད་". I don't know where in the code does this name come from. This is a more general name for the Tibetan language.
My friend says that both names are (mostly) valid, and both are used on websites when selecting the language. I guess that we should have the same name on all the platforms, but we should ask a real Tibetan speaker what is the preferred name.
I say that both names are mostly valid, because it's possible that the ⟨་⟩ character ("tseg") should be added in the end of both words, but this is also something that must be confirmed by a Tibetan speaker.
