Scoob was to've been the first Animated Scooby-Doo film to release in theatres, with the characters having an entirely different voice cast from their current voice actors (except for Frank Welker as Scooby himself), a scene in the trailer even shows Shaggy and Scooby in a movie theatre. The film was delayed from May 15th to an unknown date due to the impacts that the Corona Virus has had on Cinemas, now it's been confirmed to be skipping it's theatrically release entirely and releasing on Digital Media on that very date.

Sometime after the Corona Virus has passed, Scoob definitely needs to re-release in theatres worldwide, fulfilling the fact that it was made to be the very first full length animated Scooby-Doo film, the only theatrical Scooby-Doo films that there'd been in the past were the 2 live action films of the 2000s. It was even to've been the first time Scooby is voiced by Frank Welker in a Theatrical Film (not counting his cameo in Looney Tunes: Back in Action), after not having been so in the live action films with Welker instead providing the vocal effects for some of the monsters, it's even from an Animation Division of Warner Bros. that only aims to do Theatrical Films as far as I know of called Warner Animation Group.

Whilst heading straight to Digital Media is currently only confirmed for the US, other parts of the world like where I live could have it in theatres as intended sometime after the Corona Virus has passed, something that's already been the case with some of the films that headed to Digital Media early in the US. Of course not only does Scoob need to've had it's intended full on theatrical run at some point, but the other films of this year that skipped their theatrical run need to do so as well, for instance with fellow animated films Trolls 2 from Dreamworks Animation and Onward from Pixar: https://www.change.org/p/walt-dohrn-please-show-trolls-world-tour-in-theatres and https://www.change.org/p/the-walt-disney-company-a-summer-re-release-of-disney-pixar-s-onward
