The show is airing on Hulu on June 7, three days after it began on Channel 4 (June 4) so it doesn't meet the necessary requirement of airing simultaneously in the same language on both networks.

International co-production

Two or more networks can be added when the series is broadcast simultaneously in the original language AND a) the countries are equal producing partners or b) international networks have a producing or "in association with" credit in the original credits.

In the context of international broadcast with time difference (e.g. US/UK), simultaneously is defined as broadcast the same day.
