Language change

Wish there was an opportunity to change the language of the app. Since the app takes not the System Settings of users device, but the language of a country user sets, theres an opportunity to change the localization.
How to be with countries where two and more languages are used? Drivers set them using one language, but the app still search in the main one. Thus, some offers are missed, ive faced this problem myself. Hope it can be changed.
Thanks for the developers! Keep going!
