Found a new bug... If I have my mobile set to one language (Portguese - Brazil, in my case) and use the Garmin Connect website in another (English - US), then the phone setup changes the configuration of the website making it show up in Portuguese (apparently from Portugal, which is different from what we speak here in Brazil and why I use it all in English).
Why do the phone language has to change the setup on the website at all? And why can't I change the language of the app, instead of having to change the language of the phone (what causes issues with voice commands and the voice recognition system)?
No-go for that...
