Apologies if this has already been mentioned/asked and I missed it, but could this be due to averaging ratings across different Gigs? Mine dropped from a 5.0 to a 4.9, reflecting an average of the following:
Gig #1: 5.0 rating (633 reviews)
Gig #2: 5.0 rating (66 reviews)
Gig #3: 4.6 rating (6 reviews, with the rating dragged down by a 1-star review from someone who essentially gaslighted me but that's a whole other story)
In this case, I'm led to believe that my previous 5.0 rating was thanks to an average across a total of 705 reviews whereas now it's simply reflecting the average of these three Gigs. Perhaps a coincidence but thought I'd ask nonetheless 🙂
