I have had Prime Video for years and today I got a message that there’s not enough room & to delete other channels. I already have it. I don’t need to add it.
@sharonAD, first try a "System restart" from Settings->System or Settings->System->Power (depending on your model).
You may still have the icon on your Home Screen, but apps are removed to free up space for other apps and then redownloaded the next time they're launched. You might have the icon, but not the app's package necessary to actually run it.
i have reset my tv and even tried unplugging my tv and yet still nothing has worked. after factory restarting my tv it has NO apps at all and i still get the message when trying to download netflix that i dont have enough storage and to delete unused apps i dont understand how to fix this problem
