Binding Problems

Question

So my project is devided into parts

Service

   public class WeatherService(HttpClient client) : IWeatherService {
       public async Task<Root> GetWeatherDataByCoords(double lat, double lon) {
           var responseMessage = await client.GetAsync(
               $"{Constant.WEATHER_URL_BASE}/forecast?lat={lat}&lon={lon}&units=metric&appid={Constant.WEATHER_APIkEY}");
           if (responseMessage.IsSuccessStatusCode) {
               var res = await responseMessage.Content.ReadAsStringAsync();
               return JsonSerializer.Deserialize<Root>(res);
           }
           return new Root();
       }

        await Task.Delay(TimeSpan.FromSeconds(2));
        var data = await weatherService.GetWeatherDataByCoords(40.416775, -3.703790);
        foreach (var weather in data.List) {
            WeatherList.Add(weather);
        }
        CityName = data.City.Name;
        WeaterDesc = data.List[0].Weather[0].Description;
        WeatherTemp = $"{data.List[0].Main.Temperature} °C";
        WeatherHumidity = $"{data.List[0].Main.Humidity} %";
        WeatherWind = $"{data.List[0].Wind.Speed} Km/h";
        WeatherIcon = data.List[0].Weather[0].CustomIcon;
        IsVisible = true;
    }
}

I had to put a delay because I get wrong data sometimes

For example with the lat and lon, it should be Madrid weather and sometimes I get "Sol" in the city name

Anyway, for some reason, my collectionview doesn't want to show anything, and I don't understand, my list has 40 elemernts

and I am binding the Custom image, the temperature, and I use a Library to convert to utc

and I have data

and datetime converted
