Since mid-Jan 2022, I noticed that the YouTube Data API's list method no longer returns liveStreamingDetails.concurrentViewers. This happens to me with all live videos in several channels.

From the second doc (bold is mine):
The property and its value will be present if the broadcast has current viewers and the broadcast owner has not hidden the viewcount for the video.
As far as I know, none of the channels nor videos that I tested with have blocked viewcounts.
Is there any other way to retrieve the concurrent viewers programmatically?
