I also seem to get a random different Ambassador each time as a European member.
On the plus side, since I resumed traveling in July the Ambassador service has become much higher touch, presumably because they have much less to do right now! Have had a proactive reach out email and hand written notes at each of my last three stays (St. Regis Mardavall, Domes Miramare, Mystique where I just checked in) welcoming me back from the Ambassador service as one of my first stays back with Marriott.
