Hi @MariaCecilia22 , cancellations by guests should never count against you in regard to superhost status, but they do show on the performance page under Occupancy & Rates--Cancellation Rate. This is the "overall" cancellation rate and "is the percentage of total confirmed reservations that were canceled by you or your guests." Mine is currently 32.1% for this superhost period... yikes! What a year.
However if you check on the performance page under Superhost, you will find the Cancellation Rate that really matters--the percent of stays during the period that you have actually cancelled. Mine is 0%. There is also a note that states that "We’re waiving the criteria for cancellations and number of stays for all assessments through the end of 2021 because of disruptions caused by COVID-19."
I took a look at your reviews and didn't see any cancellation notices (they add those in if you cancel a guest's reservation), which supports your position that you didn't cancel on any guests. So my guess is that your "overall cancellation rate" is 4% (excellent in any year) and your "cancellation rate"--I think they should rename this something else to avoid confusion--is 0% (spot on!)
