I cannot reproduce. One thing strikes me as odd. Between the query to register the session and the response there seems already to be a difference of one hour ( “2026-01-05T07:00:47.91Z” “2026-01-05T06:00:47.91Z” ) can you confirm this observation (double-check)?
I do get the same time back and I am wondering if this might be a clue for us going forward in our troubleshooting efforts.
