ACTUAL BEHAVIOR

map.Pins.Remove(item) not working.

I tried the Code below:

  for (int index = 0; index < listaApreensaoFuzil.Count(); index++)
                {
                    try
                    {
                        var item = listaApreensaoFuzil[index];
                        var obj = item.latlng;
                        var LATLONG = JsonConvert.DeserializeObject<LatLong>(obj);
                        listaApreensaoFuzil[index].Latlong = LATLONG;

                        pinApreensaoFuzil.Address = listaApreensaoFuzil[index].NmInformacao;
                        pinApreensaoFuzil.Position = new Position(listaApreensaoFuzil[index].Latlong.Lat, listaApreensaoFuzil[index].Latlong.Lng);

                        map.Pins.Remove(pinApreensaoFuzil);

                    }
                    catch (Exception ex)
                    {

                    }

This code with Add instead of Remove, works nicelly. After, I click to Remove, but nothing happens. Even, a error, don´t happen.

EXPECTED BEHAVIOR

Pins removed.

I also tried on MainThread.

The Pins are beeing removed from the List, but doesn´t disappear from the map.

Is listaApreensaoFuzil pins collection?

for (int index = 0; index < listaApreensaoFuzil.Count(); index++)
{
    var item = listaApreensaoFuzil[index];
    map.Pins.Remove(item);
}

Or this is remove all pins.

var pins = map.Pins.Select(x => x); // using System.Linq;
foreach (var p in pins)
{
    map.Pins.Remove(p);
}

Yes, it is.

Didn´t work. The pins are being removed from the list, but the pins image keep displayed. I also tried the map.Pins.Clear()

This bug was fixed !! Please, check it to update this one.

Alternative solution can be to save the pins you want to keep in a seperate variable and use Pins.Clear(), this works.
