Bug Information

Version Number of Plugin: 3.0.0.12
Device Tested On: Windows 10 Dell Laptop, Panasonic Toughpad Windows 10
Simulator Tested On: N/A
Version of VS: 16.3.2
Version of Xamarin.Forms: 4.3.0.991211

Versions of other things you are using:
Plugin.CurrentActivity v2.1.0.4
Xam.Plugin.Geolocator v.4.5.0.6

Steps to reproduce the Behavior

Call CrossPermissions.Current.RequestPermissionAsync(Permission.Location) anywhere in the shared project.

Expected Behavior

Should return the <Permission,PermissionStatus> and re-prompt the user to grant/deny the permission.

Actual Behavior

UWP only: If using RequestPermissionAsync(Permission.Location), the call will always return a PermissionStatus.Granted even when the user has already denied the permissions. The user will NOT be re-prompted to grant/deny location permissions.

Code snippet

From the Plugin Permissions.UWP.cs code:

Per the above screenshot, it appears the UWP implementation of RequestPermissionAsync() is going to always return PermissionStatus.Granted.

How we are using this:
` public async Task CheckandRequestDevicePermission(PermissionType XAMpermissionType)
{
var XAMpermissionStatus = await CheckPermissionStatusAsync(XAMpermissionType);

        if (XAMpermissionStatus != CurrentPermissionStatus.Granted)
        {
            var grantResults = await _pluginPermission.RequestPermissionsAsync(new Plugin.Permissions.Abstractions.Permission[] { PermissionTypeConverter(XAMpermissionType) });
            foreach (var item in grantResults.Keys)
                if (grantResults[item] != Plugin.Permissions.Abstractions.PermissionStatus.Granted)
                {
                    return false;
                }
        }
        return true;
    }`
