Description

After running the griffin study BraveAds.CreativeAdModelBasedPredictorRecencyStudy, we determined that zeroing the last_seen_ad_predictor_weight coefficient significantly increased CTR. This issue is for updating the weight's default value client-side.

Adding missing milestone. Should currently be in 1.69.x as per brave/brave-core#24253. Wasn't moved via automation as the format was incorrect via brave/brave-core#24253 (comment).

@kjozwiak kjozwiak added this to the 1.69.x - Nightly milestone Jul 9, 2024
