My “diamonds” are missing!!!

Hi everyone!!!

In 2019 BDC introduced “Quality score rating” with stars...now I also see diamonds in listings...

Since then I have been  trying to understand why my listing is missing this quality score rating...

”All facilities and amenities are correctly configured..

All unit sizes and bed configurations are correctly”.... but still system has not evaluated my listing!!!

I would highly appreciate it if somebody could help me in this mysterious issue...

Thank you in advance and have a bet day.
