User have reported that the DVR 12 hour playback on YT 24/7 streaming option, is missing consistent timelines, recordings have been deleted (eg...recording timeline jumps from 01:00 am to 06:00am)
We have confirmed this scenario that YT does not continue the recording when there are no current viewers watching the live stream.
Note:
This does not effect YT users globally and consistently and this action can be random.
