the extension doesn't work no more. It only says "Good luck & high rating!" It doesn't indicate any sort of positive or negative delta
doesn't work anymore, fix it
doesn't work for extended period of time
Ratings are approximate not accurate. Like 10-15% less ratings are usually given on round than the extensions predictions.
It is not working!
Why isn't it working from past 1 month ?
