The Sync TV app is not supported in all countries, so it may simply not be available in your location. If you'd like to know if the app is available in your country, contact Customer Support.
First, make sure that the software on your TV is up to date. If you still can’t find the app, your TV may not be compatible with it. The Philips Hue Sync TV app is available on 2022 and newer Samsung QLED TVs in the Q60 or higher range. If your TV supports the Philips Hue Sync TV app, it will appear when you search for it in the TV's app store. If your TV is listed as compatible and up to date, but you still can't find the app, it might be that the compatible TV firmware hasn't been released yet. In that case, please contact Samsung's customer support.
