This means none of them left a review.
Sits with no reviews are only visible in the case of owners not for sitters, there’s only trace of the sit happening in the owners profile and only on the app
@Newpetlover I assumed none of them left a review, but there should be a trace of both on the sitter and HO’s profile.
I previously saw some missing reviews on both profiles, but it is the first time not seeing the HO under the sitter’s profile at all on the App.
