Whether it's a coincidence or not I'm not sure but on a booking I have for Monday the reservation was disassociated from my Hilton account and name. It was changed to be fully under my OHs name so no idea how or why that happened but perhaps something weird is going on

Never had that issue when adding a name, even on reservations booked with one person staying.
