Screenshots

No

None to show

Note:
I am using the Media Plugin v4.4.10 and that uses the Permissions plugin.

These permission requests work ok: MediaLibrary, Storage, and Location

If you restart the app after the crash the permissions was actually set and the app works fine.

Same problem here. My Code:

Page code
public SamplePage()
{
var permissionsGranted = PermissionGranted().Result;
if (!permissionsGranted)
{
//TODO
}
}

private async Task PermissionGranted()
{
var permissionStatus = CrossPermissions.Current.CheckPermissionStatusAsync().Result;
if (permissionStatus != PermissionStatus.Granted)
{
var response = await CrossPermissions.Current.RequestPermissionAsync();
return (response == PermissionStatus.Granted);
}
else
{
return true;
}
}

Application hangs on RequestPermissionAsync method.

Any ideas?
