Brave rewards has been reduced

Good afternoon,

I would like to know why the Brave Reward is not working properly?

About two months ago, they changed the reward system and since then, it has not been possible to accumulate points as before. Now it only shows the number of ads seen and the available ads have been greatly reduced. I have 6 devices logged into Brave Rewards. Today, January 26th, the device with the most ads seen has 43, and the others do not exceed 30, even though I scroll through the screens at least three times a day. I only started seeing ads after 10 or 12 days after the end of the month. Is there a new Brave policy to prevent users from getting rewards?

Thank you for your attention.
