Here is another UX design fail example. The steam app, there is no language setting in the steam app. People can change theirs prefer language in PC version of the steam. However, you cannot change the language on the mobile app.
The solution to this UXD fail is to link PC steam language setting to steam app setting, which they did not modify yet. So, what I do is to change my language setting of my iPhone. The steam app will automatically change to the language to the language of my phone.
