Brave rewards amount reduced To 0.025

Now a day i am seeing lot of problem in this brave browser.

1.) No ads is been displayed now and then ( i use my the browser around 6 hours a day)

2.) Brave reward is not payed correctly.

3.) And the main problem is that the brave ads reward is been reduced to 0.025 and not even seeing the 0.050 ads any more what even ads i get is only 0.025.
and as per your guys logic the brave ads rewards will increase or decrease according to the ads. then i just wonder why i haven’t seen any ads on 0.075 .

And is not fare brave please reset the ads Reward to 0.050 Cos 0.025 is very low. And i just i want to know why am not even seeing a single 0.050 ad after the new update???
