Wrote a review from Galaxy, but since my Galaxy UI was set to Polish my review was marked as written in Polish, despite having been written it in English. Since I have the website set to English it didn't appear under reviews for me at all, because "written in English" was checked as default.

The consequence of this design would be that a lot of reviews written in English by people who have their app UI in non-English are not visible for English speakers. Since English is the lingua franca, I suspect this is not an isolated incident - there's a lot of foreign language speakers who write their reviews in English for the benefit of the international public, and they might be unaware of this behaviour.

A simple checkbox for the language of your review would solve the problem, instead of taking it from the UI which isn't really relevant.
