After the app rating was down to about 2.8 stars on Google Play Store recently, it is now at 4.1 stars. Latest ratings seem to be from September 2022 though.
Looks like they've deleted all the 1-star ratings that had been recently added.
It seems to me like it's the US which is severely lacking in customer protections, allowing the Playstore to make deals with Reddit to fudge the ratings.
