I am a TRS myself since 2018 and things have been really great for me even since, until around end of January 2023, I noticed that orders stopped coming the way they used to, I've been in the decline until now, but I do think that I actually know why thanks to @frank_d post, I have canceled two orders from first time buyers, which wasn't my fault and CS took care of it as it doesn't affect my metrics, I also had two or three reviews that were 3.7 stars or so. I just contacted a SM for my first time to know how my internal BSR ratio is doing to see if it's due to that or something else that is impacting all of us by mistake.
by the way, thanks to advices from frank, I became a top rated seller! he is a really great person!
