Hi Toengel, I bought an exhibition sample 55PUS8808/12 at the store. When I first used it, I was very surprised by the instant response on YouTube. It was a pleasant surprise for me. The next day, update 101.002.038.208 arrived. Now youtube is not responding. While studying some articles on the Internet, I found that there is information that the youtube service still opens without problems on some older devices. Perhaps if you go back to the previous version 001.001.091.215, this will be confirmed. I would risk returning the old firmware. And if that doesn’t work, then you have firmware 101.002.038.23 on your website. P.S. Google seems to be aware of this problem with some devices and promises to overcome this conflict. But judging by my TV, their task is not completely solved yet. That’s why I asked for such an old firmware.
