Update: In a statement provided to US Gamer, Mojang said it "no plans" to take over Minecraft: Story Mode from Telltale.
A news update over on Minecraft.net has revealed support for Minecraft: Story Mode will end on 25th June 2019. Mojang, on behalf of the now-defunct publisher Telltale Games, explained how both seasons and all episodes would need to be downloaded before this date:
“On behalf of the publisher, Minecraft: Story Mode - A Telltale Games Series, Season 1 and 2 will no longer be supported on June 25th, 2019. If you have purchased these seasons, please download all remaining episodes prior to the service being discontinued in June."
"So if you own either season of Minecraft: Story Mode on Microsoft Windows, macOS, PlayStation 3, PlayStation 4, PlayStation Vita, Wii U, Nintendo Switch, Xbox 360, Xbox One, Android, or iOS, you have until June 25th, 2019 to download the episodes. We’d recommend checking you have all the episodes downloaded!"
As noted, this applies to every version of the game. So, if you own either or both seasons of Minecraft: Story Mode, it's recommended you check now to ensure you have every episode downloaded before 25th June.
