We have some code (in Sitecore 9.0.1) that identifies our contact (and saves some data in facets):
Our code sees to work. Our contact is saved to the database correctly and we can find it in the experience profile with all facets filled. Updates also work - the contact is recognized as being "not new" and updated accordingly.
Xdb.Collection database I can find my contact's identifier(s) with indeed the one with my source and
IdentifierType 1. So that seems fine as well.
The problem is that although I can find my contact in the experience profile list & details (with everything filled perfectly), the timeline (also showing correct data) still says it is an unknown contact.
I did check the "internet" and found this answer on SSE (where else..), but that is for 8.2 and doesn't seem to be the solution for v9.
Does anyone know how to get a Sitecore 9 to show "known contact"?
