Fenix 7X and Tactix 7 Language Not Changing

Two users reported that the language displayed on their device is persistently the default language (English) and not the language in their device settings (Italian and German). One user has a Fenix 7X Pro Sapphire Solar, and the other user has a Tactix 7 Pro (I understand these are essentially the same). They only experience this problem with my watch face app and not other CIQ watch faces. It works fine if I test it in the simulator and on my own device (fenix 7S pro sapphire solar).

Any advice on what could be causing this problem or how to troubleshoot?
