Certain Video Ad Breaks metrics return no data, seemingly block data from other metrics from appearing

This specifically seems to affect post_video_ad_break_ad_impressions, post_video_ad_break_earnings and post_video_ad_break_ad_cpm under Page insights -> Video Ad Breaks metrics.
A request in the form of
GET [page_id]/insights?metric=post_video_ad_break_earnings&period=day&since=1711954800&until=1714460400
returns
{
"data": [
],
"paging": { ... }
}
This doesn't change based on whether the period is set to day, lifetime or omitted. Similarly, it doesn't change with the value of since nor until, nor does it change if they are omitted.
When mixed in with other (older?) metrics, which work in isolation, either no data is returned for the affected metrics, or only data for unaffected metrics is returned, which seems to vary request to request (i.e. the same request may produce varying results when repeated).
This seems to affect multiple pages, authenticated by multiple users.
Question: am I doing something wrong? Am I omitting some parameter that is not (well) documented?
Due to the random interactions with other metrics this feels like a bug, but there no longer exists a path to report a bug in this product.
