I'm receiving an null reference exception from SfComboBox when updating an item in the bound ObservableCollection DataSource. This is working fine in Android, but crashes in ios. Any help will be greatly appreciated. I noticed this in 16.4.0.54, but still see it after upgrading to 17.1.0.43.
Object reference not set to an instance of an object
