I have contacted customer service about this too.
I host a room in my home for long term stays but didn't have enough ratings this last quarter for Superhost status.
However, I handle every pre-guest arrival, checkin and checkout as a co-host Q2 and earned him Superhost status because he is the owner of the listing.
They may need to revise their system because this doesn't seem balanced.
Keep sending feedback on every survey you get. I think if there's enough feedback, they will seriously look at the issue.
Keep on getting those shoutouts and 5 stars,
