Promoted Content in Brave News is Not Being Rewarded

Brave News occasionaly displays Promoted content. But they are never rewarded.

This the error that I get in the logs-

This error is persistent as far as I remember, for few months atleast.

Region: India

Brave 1.31.88 Chromium: 95.0.4638.69 (Official Build) (64-bit)

NTP Sponsored Images (IN) - Version: 1.0.536 (from brave://components/)

I receive NTP Ads and Ad notifications both and get rewarded for them. Problem is only with Promoted contents in Brave News. Could it be that Promoted contents reward only in some regions? @steeven @Mattches
