Title sums up pretty well.
I played a little when Genshin Impact was launched and I chose to wait for a European language localization for the PS4 trophies list since I couldn't understand any of them.
A year has passed, and I still have the Chinese list which sounds like a bug to me. Also because its trophies are listed in English on PSN Profiles and other sites.
Is there a way to change PS4 trophies language from Chinese?
