Not receiving rewars notifications

Dear Brave staff, my ads counter increases slowly and states that I’m receiving ads, but I can not see them (I don’t see the notification on my desktop).

This is happening since november 1 of 2021. Occurs to my 3 devices connected to Brave and even to many friends that live in my same city.

Please your prompt support

same with my 3 devices, barely ads pop out. Rewards per day has decreased drastically.
