I am having the same pop up come on my screen. It comes on for 15 seconds and goes away for 2 minutes and then comes again. This has been going on for the last two weeks. Does anyone know how to get rid of these. I do not have a smart TV.
If these "popups" are more banners, look in your TV settings to verify that your TV is in "home" mode, not "store" or "demo" mode.
If the above is a RokuTV, usually will require a Factory Reset and selecting the home mode during setup and verification.
Feel free to post a screenshot if you can catch it if you still need more help. Or provide TV model number and description of what the pop-up says.
