If Disney Plus is not working on your Samsung TV, you need to power-cycle your TV. Unplug your TV from the wall and wait a FULL 60 seconds. While you wait, press and hold the power button on the TV for 30 seconds. After the minute is up, plug your TV back in. Not only does disneyplus.com/begin allow you to watch on four devices, you can set up seven different profiles. The primary profile is the account holder's – and you can't change that one unfortunately. Disney+ subscribers are able to cancel their subscription at any time. Please note that cancelling your Disney+ subscription will not delete your Disney+ account or the Disney account you use for other products and experiences from The Walt Disney Company, if applicable.There's currently no way to cancel your Disney Plus subscription through the mobile app. If you signed up for Disney Plus through a third-party service, you may need to cancel your subscription through that company's website instead.
