Experience Editor's unexpected behavior

Question

I have the below situation.

I have a .NET Core application that sends a Contact with Facet data to xConnect to show interest in a category (using profile keys).

A Sitecore website, on which I track a Contact, to show a commercial based on interest shown in the category.

It worked first time when I tried, i got the commercial that i was expecting. Than i updated my profile keys again in my .NET Core application, and i can see my ContactBehaviourProfile being updated to the new interest.

However, when i log into the Sitecore website and start tracking the Contact with changed interests, the commercial from the first setting poped up.

I have my rules set up like this:

I don't have much experience with Sitecore but heard somewhere that Contact data is flushed to xDB when session ends,

Does Sitecore 9/ xConnect have the same behaviour?

EDIT:
I tried updating and using the RemoveFromSession method. I am now calling the method before returning the view but i am still getting the old Contact.

    [HttpPost]
    public ActionResult Track(string email)
    {
        if (Request.Form["Email"] != null)
        {
            if (Request.Form["Email"] != "")
                Tracker.Current.Session.IdentifyAs("email", Request.Form["email"]);
        }
        var contact = Tracker.Current.Session.Contact; // this is for debugging
        Sitecore.XConnect.Contact Contact = GetContactWithBehaviourProfile(email); // this is for debugging
        FillViewBag();
        var manager = Sitecore.Configuration.Factory.CreateObject("tracking/contactManager", true) as Sitecore.Analytics.Tracking.ContactManager;
        manager.RemoveFromSession(Sitecore.Analytics.Tracker.Current.Contact.ContactId);
        return View();
    }

Answer 1

SC 9 is flushed immediately unlike previous versions. With your particular issue, my guess is that you didn't update the Tracker's Contact (assuming that you are doing this on the same tracker session). This means that updating the xConnect Contact does not automatically update the Tracker's Contact. This is mainly true on v. 9 Initial Release. So, you must update your Tracker's Contact also when updating xConnect's Contact. However, in v9 Update 1, Sitecore has provided a new Sitecore.Analytics.Tracking.ContactManager method :

manager.RemoveFromSession(Sitecore.Analytics.Tracker.Current.Contact.ContactId); // Use tracker ID, not xConnect ID

to allow the contact to be reloaded in next request. Find out more here.

UPDATE

Here's how to access the ContactBehaviorProfile facet as shown in the Sitecore Docs. At this point, you should just be able to update the data but of course it depends how much data you need to update, it may get a bit more complex.

var xConnectFacets = Sitecore.Analytics.Tracker.Current.Contact.GetFacet("XConnectFacets");

ContactBehaviorProfile cbp = xConnectFacets.Facets[ContactBehaviorProfile.DefaultFacetKey] as ContactBehaviorProfile;
