The above is missing and IMDB shows it was released in the UK 16th December 2019, the previous 8 are there.
What IMDB is shows the US air dates. Sky has not shown the Crisis on Infinite Worlds episodes, so it is most certainly not missing.
There is no confirmed air date for the continuation of the Flash, Arrow and Supergirl from Sky. Best guess is that it will be February.
Ah, looks IMDB made an error.
Thank you, was worried I missed something.
