Garmin Bounce - set weather unit to Celsius not working

Hello,

I got two Bounces for my kids last December. All works great except that the temperature unit for the weather in the watch is stuck to Fahrenheit.

In the watch settings, under system - units, we selected Km and Celsius, but the temperature of the weather app is always shown in Fahrenheit.

There is no settings for units in the Android app.

We are Europeans living in NY and we hate the Imperial system: this is most likely a bug already signaled to Garmin, is there any plan to fix it or does anybody have any workaround?

Thanks!
