This video is working for me on MacOS in Strict mode and Standard mode, so it might be related to the media stack rather than ETP. Alternatively, it's possible that the page ends up using a different ad-service than Ads by Google for you, which SmartBlock does not help with.

Oana, do you see any interesting notes in the devtools web console?

Not anymore, the video plays now with ETP - Strict.
