Most of the recent DC films, like Shazam! and Aquaman, that have been part of that universe, have largely ignored that and focused on individual stories that don’t require any sort of continuity.

While the new film will certainly be part of the DC movie universe, as it stars Margot Robbie as the character she started in Suicide Squad, it’s unclear how much any of that will matter.
