A streaming service essential has now found its way into Disney+. Disney is rolling out a server-side update to add the missing "Continue watching" section. A strange omission that's thankfully being added now. There's nothing you need to do; you just have to wait for the update to head your way. It will be coming to all platforms Disney+ is available on.
And once you get it, you will see a "Continue watching" row on your home screen. It will display shows or movies you've recently started and how far along you are in the episode or film. When you tap on a specific title, it will then pick up where you left off.
