Sorry to hear that you are having problems removing the TV Anywhere app on your Samsung Galaxy S6.
I use a Virgin Mobile S6 Edge and can see that there is no Uninstall button within the app or when accessing it via the Application Manager as well (only a Force Stop, Uninstall Updates, and Disable option), but found two ways around this:
I can uninstall the TV Anywhere app by going into the main Apps screen to the TV Anywhere icon and holding in this icon for a few seconds then dragging it to the Uninstall bin icon at the top of the screen.
Another way that works is going into the Play Store, search for TV Anywhere and it will show that it's already installed and give you options to Open or Uninstall--you should be able to press uninstall and this should remove the app from your phone.
Please let me know how you get on with this.

Thanks for the reply. Going to the app store just let's me re-enable the app then either update or open. No uninstall option is available. As for holding the app to uninstall that just seems to remove it from the screen desktop not remove it from my phone. Thanks for the reply
