The bug that’s causing rows in Discover, including New & Updated, to update less often is also causing us to deliver fewer impressions than reported for some Sponsored Row campaigns – in most cases under 10% but in a few cases up to 20%.
We’ll have a fix on December 18.
We’ll refund impacted developers for the portion of impressions they didn’t receive between November 30 and December 18. Once the fix is live, we will roll out refunds that will be automatically issued to the original payment method.
