I have just logged in to Pokémon Go and it stated I had achieved a bronze medal for Wayfarer agreements. I thought this was odd since I had been on silver!!
In checking it appears to have reduced back down to the number that I was on before the points were changed on here?
I was on 825 on 20 May and today I’m down at 475?
Same problem.
From approx. 730 to 331…
And i wanted to get the gold medal until saturday to get wayfarer stuff at Go Fest Copenhagen 
Edit: my girlfriends medal to…from approx. 1000 to 350…wow
Wow, we were just discussing this happening on the Wayfarer Discussion Discord! It happened to @flufybunny44 as well. It looks like the agreements that had been added to the medal for reviews made in fair or poor status have been rolled back?
@NianticTintino this does not seem to be expected behavior from the ratings adjustment post.
Maybe a mod should move this to Bug Reports & Technical Support ?
My medal was reduced by about 50 points.
Got my platin medal on saturday, now changed to gold.
I’ve moved my original post. Hope it is a bug !
I have been going up in my wayfarer medal recently until today. Today is dropped from 902 to 561. Can anyone explain how that happened? I contacted Niantic support, but they might not respond.
There is another post on this topic.
Hoping we can get all the reports into one topic and get the topic moved to Bug Reports & Technical Support
1365 to 855… 
Thanks for the report, folks.
We are aware of this issue, and our team is looking into it as we speak. We appreciate your patience while we work on a fix.
The same thing happened to me. I went from gold to silver medal. I had approximately 1000+ down to 700 ish.
Have seen at least one person report the medal going back up after the drop. That was fast!
Thanks for the confirmation.
I can confirm that we have shipped a fix for this issue.
