I noticed this issue since yesterday. I have a Panasonic smart tv, but when I go to the Youtube app, and I select a video, I press the OK button to start playback, but now it isn't working. I can move from video to video, arrow buttons work fine. It is not the remote, the Netflix app and Tunein apps, work fine, the OK button will start playback fine in those apps. It is just the OK button on Youtube app, if i go to search a video I can move from letter to letter say I select A for example, and when I press OK button to enter letter A, it doesn't work. Is anybody else with a Panasonic Smart TV, having this same issue?
