Simply Click Reward Points Error or Changes

Need help in Sbi Simply Click Credit Card because earlier, I am getting 10x reward points using it on Amazon as preferred merchant but from the month of November, I am getting only 1x reward points. Is their any changes about which I am not aware or this a system error of Sbi. I feel their are some other Dimers also who are not aware of this and request you all to check your Sbi Simply Click rewards and calculate according your spending.
