MacRumors:

A trailer for the second season of Apple Original series “For All Mankind” has today been shared on IMDb, but it has not yet been officially released by Apple.

Apple TV+ trailers and promotional videos are usually shared on the ‌Apple TV‌+ YouTube channel and via the ‌Apple TV‌+ newsroom, but the “For All Mankind” season two trailer has yet to appear on either. It is possible that the trailer has been prematurely uploaded to IMDb today ahead of an official announcement from Apple. A release date for the second season has also not yet been announced.

Very odd to not see this released on the official Apple TV+ YouTube channel as of this writing but it is on the Apple TV+ Facebook page. I watched the first season and, while I don’t think it rose to the level of great TV, I’m still looking forward to season 2.

UPDATE: It is now on Apple TV+ YouTube channel.
