Weather update still doesn't work (amazfit bip, app 8.12.1, dark sky, Huawei mate 20 x, Android 9.1). Not automatically nor manually ("sync failed")..
The same for me if i use DarkSky as weather service.
If i choose 1 of the 2 others it works (the first with 4 days is very bad by the way).
I have now activated an API number for OpenWeatherMap and use that.
It works ok, but not every hour, just about every 2 hours.
I do hope that DarkSky is going to work soon again.
