I would like to change the language to German, mostly for common names, but the only languages available are Basque, Galician, and English (device language).
The mobile app automatically picks up and runs in whatever language your device is set to, so to run in German, you need to be running your phone in German, then it should switch over. After switching your device, you likely need to close and restart the app.
Those 2 languages are listed separately as they are things the app is translated into, but many mobile operating systems do not offer them as option to run the device in.
Oh OK, thanks!
This is not a bug report then but a feature request. I’ll try to post it on the appropriate category.
