Back again after 3 years.
I just posted in the Royal Ambassador 2023 forum.

In short:
Hotel is fully operational. They used the time for improvements. English skills of the staff are better than before. Service in the club lounge is really good. Breakfast is very good, lacking in a few minor areas (like bread is a bit stale and mushy). Food in the club lounge of high tea and happt hour is ok, not great. Overall a very good experience.
