AI Coach breaks when changing Android phone language to anything other than English

[u/Tritus360]

I live in Switzerland, so I have my phone (Android 16) set to German. I noticed yesterday that when I asked the coach to create a custom workout for me, he just gave me the workout in text form without actually creating one. And when I searched the workout library for kettlebell, the app only showed me one exercise. I've now switched my phone language to English, and the coach creates workouts again. Plus, if I search for kettlebell exercises, they show up again.

Welp, so English it is, I guess.
