Today I installed the update on two PCs and they both stopped showing sponsored images when a new tab is open. According to this https://sampson.codes/brave/ads/my_region/ there should be sponsored images ads. I’ll try later with another PC as well, running under a different network/ISP to see if it’s a widespread problem.
EDIT: Notification ads seems to be working fine.
