Update an already injected service DryIoc c#

Hi I have a situation where I need to update a service that I have injected.

When I first launch the app I have something like

public class MyService:IMyService
{
  public string ValueAPopulatedBeforeLogin { get; set; }
  public string ValueBPopulatedBeforeLogin { get; set; }
  public string ValueCPopulatedAfterLogin { get; set; }
 }
container<IMyService,MyService>();

1. Start the app
2. ValueA and B are populated ValueC IS NOT
3. Login now valueC is populated

Now I need to update MyService but doing

 container.ClearCache(typeOf(IMyService));
 container.UseInstance(MyService);  //with new ValueC updated value

however the new property has not been updated.

How do you update an already injected service? Is this possible?

thanks
