If there is an issue on the Zattoo app of your Samsung Smart TV, please go through the steps of troubleshooting:
1. Delete the Zattoo App and reinstall it:
- Turn on your device and go to the Smart Hub Symbol
- Go to the Samsung Apps
- Search for Zattoo and select the App
- Delete the App and reinstall it by pressing the arrow button above the App-Icon and opening a little menu with the delete-option

2. Update the Firmware on your TV:
Go to "Menu" > "Support" > "Software Updates" > "Enter"
In case you have a device from 2012 and the Software-Update is not available with these instructions, you will need to update your TV manually with a USB-Stick. you can find further instructions here: http://www.samsung.com/de/support/ (enter the name of your TV model).

4. LAN-connection instead of WLAN.
The App will only work properly if your Internet connection is stable. For a stable connection especially on big screens such as Smart TV, Nvidia Shield, Apple TV or Amazon Fire TV we recommend the use of a LAN-connection (cable). WLAN (wireless connection) can be affected by many factors and is more susceptable to errors than a cable connection.
