BRAVE REWARD ( BAT) to USD estimate Reduced.?

This is to report that I noticed that Brave BAT calculation is not ACCURATE. Rewards BAT to USD showing on my browser deducted each day. Now it is a couple of days in a row. I am using Brave for some time now and I also click on the adverts when they pop up.

Do you have auto-contribute still enabled? It is enabled by default. Brave may be tipping creators on automatically on your behalf.
